Nose Vomit
Not me, but a friend of mine got especially drunken one Friday and there was pretty much a day and a half of him feeling pretty rough, voming periodically etc etc. Standard stuff.

On Monday, fully recovered we're walking into uni and he stops to blow his nose. In the resulting mucus he found one of those small, heavily deep fried and very solid chips that are present toward the end of a take-away.

Apparently, he had vomed his on-the-way-home-drunk takeaway through his nose leaving this little morsel lodged in his nasal cavity to be discovered over 48 hours later. The harrowing combination of fried potato and nasal discharge caused a significant regression in his health and he had to return to bed for the rest of the day.
