Sometimes, students say what you wish you could.

I do a little mark-and-recapture lab using cheapie pet store crickets (the kind you can buy to feed your lizards or oscars, those kind).

I had the different "populations" to be sampled in big rubbermaid tubs. One of the guys in the class leaned over the tub, then straightened up with a sour expression on his face and exclaimed, "These crickets smell like BUTT!" (Remember, these are mostly 20-22 year old college students)

(it was all I could do to keep from giggling. But yeah - that was what the whole pet store smelled like. I spent 20-25 minutes there yesterday with the beginnings of a migraine. And there was this cockatiel that kept repeating his song. Over. And Over. And Over. And Over. And the cricket-wrangler was talking to a couple of college kidz who came in to play with the puppies, so it took a lot longer for her to wrangle the crickets than usual. No wonder the secretary thought I looked like I was suffering when I came back to give her the receipt.)
