Hehe...sounds like the TXan must have had a bad night (or a really bad student :-). My favorite one is to say "ooh, look how many swimming pools there are down there" (this in in Florida BTW). Or.."ooh look, there's a naked woman down there!" Apologies any female readers. Usually, I find most students are more than worried about the traffic in the pattern and this can be enough of a distraction at times!
Happy flying y'all
