Remember you MUST pick one or the other.
1. Would you rather wear your last Halloween costume or last nights sleepwear for a whole year?(tell us what is is)
Sleepwear. Blue pajamas & thick fluffy socks. It was cold.
2. Would you rather be naked in stocks/pillory in a public place for an hour then get your clothes back or wake up at a 2 hours walk from your house naked with just your house key?
The stocks 
Both would be mortifying but at least after an hour I'd be out.
3. Would you be more embarrassed if your mom or dad caught you masturbating?
Dad
4. Would you rather be hypnotized to act like a dog or a baby?
Dog
5. Would you rather be the only one naked at a party fully of guys or girls?
Party of Guys. Either would be embarassing but I imagine they'd enjoy the view more if I had to choose.
6. Would you rather go to the doctor to remove a vibrating egg from your ass or wait a week until it falls out?(its on a low vibrate the whole time)
Have it removed. I'd probably wait a day trying to get it out but would want it gone well before the week was over.
7. Would you rather do a lap dance or a pole dance for your celebrity crush?
Pole. I can't imagine myself being much good at either though
8. Would you rather only be able to have sex after eating an onion or a can of beans? (onion = bad breath and beans = farting a lot)
Beans. They really don't really make me gassy.
Both guys and girls can answer the next 2 just for fun
9. Would you rather have a 3 inch penis or an 15 inch penis when erect?
I'd rather not have either but I'd say 3 if I had to. You'd need three legged pants for 15 
10. Would you rather have an A cup or an F cup bra size?
A cup. I bounce enough already without getting bigger
11. Would you rather have a unicorn horn or a fluffy bunny rabbit tail?
Bunny tail
12. Would you rather be strip searched at an airport or the entrance of a nightclub on the spot?
An airport. No bar is worth a strip search to get in but a holiday might be worth the embarassment
13. Would you rather wear a butt plug or a ball gag for 5 hours?
...A plug if I had to. I couldn't keep a gag in that long.
14. Would you rather a one night stand find out you wear the opposite genders undies or that you grow a jungle down there when its time to strip?
Underwear. Wearing boxers wouldnt really be a big deal.
15. Would you rather give oral to the next stranger you see or the last person you texted?(who was it)
Last person I texted. She's a friend
16. Would you rather your results of this quiz to be posted on your Facebook or on your kitchen fridge for a month?
Fridge. I don't much care for facebook and don't need everyone I know seeing these truth threads I occasionally answer.
