Title text: Don't need any, thanks. I have a backscattering fetish.
Many people are upset about airport security policies that mandate the use of backscatter X-ray machines, since the machines can create an image of the subject naked. Black Hat is selling Viagra for men a means to thumb their noses (so to speak) at the system by forcing the security guard to see them with erections. Judging by the security guard's thought bubble, he indeed is not looking forward to the images.
At the title text, Black Hat explains he has a fetish with getting X-ray scanned, and so thus doesn't need Viagra to achieve the above effect.
- [There is an airport security checkpoint where a queue of ten passengers is waiting to go through a backscatter x-ray scanner. Near the back of the line, Black Hat is standing next to a stand which says "Viagra $20". One passenger next to him is drinking a glass of water; another is contemplating the sign.]
- Security Guard (thinking): Oh god.
