Gotta love the students that get English teacher jokes.
"Last weekend, I was cycling on the bike path heading to the Botanic Garden," I tell a student before class, "and I took this picture. What do you think?"
She looks at the picture, then at me. "A picture of a porta-potty?" she says. "You need a hobby."
I try again later.
This student looks at the picture and laughs. "What a dumb ass!" she says and calls over a friend. "Hey, check this out. Look how someone wrote the word here."
