Would you...

Sell your positive pregnancy tests for money? I've never heard of such a thing & I saw a legitimate add on Craigslist of a woman willing to pay 50$ for a positive pregnancy test to show her boyfriend. Honestly, I would pee on a stick for 50$ anyday, if I were pregnant. I would feel bad for the guy obviously, but I'm pretty sure it won't be long until he realizes she's not really pregnant lol. What do you guys think?
