Student: Sir, can I ask a question?
Teacher: Go ahead.
Student: How do you fit an elephant into a refrigerator?
Teacher: I don’t know.
Student: Well, first you open the refrigerator, then you put the elephant in, and then you close the door.
Teacher: That’s not funny.
Student: I thought it was.
Teacher: Okay, fine. How do you fit a donkey into a refrigerator?
Student: That’s easy. You just take the elephant out first.
Teacher: (sighs) I see what you did there.
Student: I have one more question. Why couldn’t the donkey go to the lion’s birthday party?
Teacher: I don’t know. Why couldn’t he?
Student: Because he was in the refrigerator.
Teacher: (groans) That’s enough.
Student: Just one more question. How do you cross a river full of crocodiles?
Teacher: I don’t know. How do you?
Student: You swim across. All the crocodiles are at the lion’s birthday party.
