I have discovered that if you say you're doing it "for SCIENCE!", you can get away with a lot.
Not in so many words, and it's not always a positive thing, but hell.
Set your neighbor's dog on fire? FOR SCIENCE!
Act like a dick to 12-year-olds on the internet? SOCIAL EXPERIMENT!
Streaked through the mall? Pshaw, you plebes, it's a gauge of peoples' reactions to public nudity!
Et al., et al.
