I went onboard a new navy ship as Marine guard. A bunch of newbies, going to sea for the first time. The rule was, if you puked, you cleaned it up. If you didn't but laughed at someone who did, you cleaned it up. Try and clean up someone else puke without adding to the mess.

No, I did't laugh, and I didn't eat the lunch they served just before leaving the dock, either.

Chili.

Still, I've seen some drunks puke just from one not so drunk guy making puking noises.
