I told a student that I wouldn't be coaching cross country this year. "But you should sign up. You could get your girlfriend to do it, too. It would be fun," I encouraged him.

"But then we'd get all hot and sweaty and dirty," he countered.

I stalled for a couple seconds as I held my tongue. Finally I settled on, "I think that's okay in this context," before walking away quickly.
