A Little ESL Humor: Beware Seven!

Once in a while I look at my students and with the darkest of looks, and ask them:

Which number is the most dangerous?

Most think it’s a silly question, but an intredpid few venture a guess.

Then I reply:

Don’t you know? It’s 7! 7 ate 9!

7-ate-92

Cue the groans.
