Got the big word used! It was a very bizarre texting conversation, but that's pretty normal with this coworker.

Me: "Are these your dark tan pants on the back of the lab door?"
Him: "Pants? Are they camo?"
"They might be camel."
H: "Must be Neal's. Are they camel skin?"
"Neal said they're not his. Dromedaries need not apply."
H: "What about other ungulates?"
"Only if it is hippopotomonstrosesquipedalian."
H: "I ride one of those to work every day."
"Do you need to feed it cheesecake?"
H: "Beer and brats"

I know it seems like a fake use of the required phrases, but he started it with his randomness. ;-)
