Title text: To anyone I've taken on a terrible date, this is retroactively my cover story.
Megan's sister has a crush on Cueball, but Cueball doesn't feel the same way about her sister. To alleviate the situation without hurting Megan's sister's feelings, Megan wants Cueball to deliberately take her sister out on a bad date to convince her that Cueball is not worth dating, so that her sister can move on without rejection. Cueball becomes extremely excited at the thought of deliberately having a bad date, especially because he has had some awkward dates in high school. The joke is that people often want their dates to go as well as possible, and this is a rare opportunity to do the exact opposite.
The title text says that Randall uses the excuse of "I was asked to take you on a bad date" to "explain" bad dates he's had with people.

- Megan: I figured you could handle it.
- Cueball: One of my classic high-school dates coming up!
- Megan: Oh God. Don't overdo it.
