&lt;div&gt;No, the comic is funny because many geometrical theorems prove something along the lines of &amp;quot;With a compass and straightedge you cannot construct...&amp;quot; (e.g. a square and a circle with the same area) If you have knowledge of this type of proof, the humor is that you think he's about to talk about something that is impossible in geometry, but really he's talking about the inapplicability of geometry to real life. This is often a difficulty with nerds and brainy people, they try to apply their theoretical knowledge to human relationships and fail.

:And then there's the converse: people who are able to apply theoretical knowledge and succeed. [[Special:Contributions/76.106.251.87|76.106.251.87]] 04:33, 5 June 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
The explanation mentions that there are &amp;quot;three such constructions&amp;quot;, but doesn't go any further.  What they are should at least be addressed (or linked to), even if we're not going to elaborate on the &amp;quot;why&amp;quot; of their impossibility.  For the uninitiated, they are squaring the circle, trisecting any angle, and doubling the cube. [[Special:Contributions/76.106.251.87|76.106.251.87]] 04:33, 5 June 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
If such constructions are &amp;quot;impossible with the use of modern algebraic techniques,&amp;quot; then why don't we just use older algebraic techniques?  ;){{unsigned ip|213.203.138.251}}&lt;br /&gt;
:Those &amp;quot;modern algebraic techniques&amp;quot; just did prove that you can't solve this constructions by using only &amp;quot;classical geometry&amp;quot;.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 18:14, 29 June 2013 (UTC)&lt;br /&gt;

I tried forming a club for compasses and straight edges but no one signed up :( ~JFreund&lt;br /&gt;

Could the “most awsome birthday party“ bear another deeper meaning, for example be analogue to the rational polynom with rational coefficients?&lt;br /&gt;

Could this &amp;quot;most awesome birthday party&amp;quot; be a reference to Stephen Hawking's party for time travelers?&lt;br /&gt;

And I hear if you have a basic understanding of computer systems and know a reservist Colonel, you can hack into the flight schedule, reserve two fighters fully loaded down with as much ordnance as they can carry, and go on a rescue mission to save your father who was shot down in disputed airspace.

&lt;br /&gt;
The mention of &amp;quot;planes from different eras&amp;quot; alludes to the fact that military aircraft are often still in use after a much longer time than they were originally designed for. Examples of this are the US Air Force's B-52 bomber, first introduced in 1955 (62 years before the publication of this comic) and the C-160 Transall, which has been in service in, e.g., the German Luftwaffe, since 1967 (50 years before). Additionally, aircraft museums typically house military aircraft from previous eras, such as from WWII and the Cold War, to show the evolution in aircraft design and to showcase technological advances.&lt;br /&gt;
&lt;br /&gt;
It struck me as more, if not entirely, the latter. I didn't perceive any allusion to the fact that &amp;quot;military aircraft are often still in use after a much longer time than they were originally designed for&amp;quot; [[Special:Contributions/162.158.74.51|162.158.74.51]] 05:13, 15 June 2017 (UTC)&lt;br /&gt;
:I've removed the C-160 Transall because the German Luftwaffe doesn't belong to any US Air Base. But have you ever seen a B-52 bomber? It's a really historic plane.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 12:31, 15 June 2017 (UTC)&lt;br /&gt;

;Implication of pursuit?&lt;br /&gt;
The implication is that there was no museum to begin with and Cueball went to observe the actual air force base and '''''is now being pursued by the military'''''. &lt;br /&gt;
&lt;br /&gt;
I don't think there's anything to credibly suggest Cueball is being pursued. Hearing helicopters implies they are close enough to perceive a military operation of some sort, but it could easily be launching aircraft departing to another destination as it might be pursuit of Cueball. Is there anything to justify the last 7 words? [[User:JohnHawkinson|JohnHawkinson]] ([[User talk:JohnHawkinson|talk]]) 01:54, 15 June 2017 (UTC)&lt;br /&gt;
:Realistically, they would be pursued by MPs and probably local police in vehicles, not helicopters. But if Cueball was (intentionally or accidentally) able to get on a base and into a hangar where they were loading ordnance onto jets, they might very well include air units in the search for him. The bigger question is where was Megan while Cueball was inside, seeing as she was close enough to accompany him in the not-so-tactical escape.

::I think you mean &amp;quot;ordnance,&amp;quot; not &amp;quot;ordinance.&amp;quot;  The two words mean completely different things. --[[Special:Contributions/172.68.58.101|172.68.58.101]] 12:31, 15 June 2017 (UTC)&lt;br /&gt;
