leaving a restroom with toilet paper hanging out of your pants

Any of the above.

But I always worry about the toilet paper problem, ever since I saw it in Smoky & the Bandit.

talking in a noisy place when suddenly they turn the music off

in order from most to least...
1 porn
2 TP
3 wrong
4 wallet
5 music

The last one. It's a horrible thought, which is why I duct tape mine to my stomach. Lol jk, but seriously the last one is probably the worst.

It would have to be leaving a restroom with toilet paper hanging out your pants.

Definitely a tie between the first 2. The last 2 have actually happened to me...
