The teacher is asking a geography question: 
– Mary, where is the English Channel?
– I don’t know. We can’t get it on our TV.
(English Channel = Lamanšský prieliv)
The teacher asked a student, „John, name two pronouns.“
John, who suddenly woke up, said, „Who, me?“
The teacher said, „Today we will review our tenses. Now, if I say ‚I am beautiful‘, what tense is it?“
A student replied, „Obviously the past tense.“
