Sorry but I don't know English jokes. I searched jokes and I found this:

,,Can a kangaroo jump higher than a house? Of course, a house doesn’t jump at all."

I think this is better:

,,Doctor: "I'm sorry but you suffer from a terminal illness and have only 10 to live."

Patient: "What do you mean, 10? 10 what? Months? Weeks?!"

Doctor: "Nine." "

I once had an extremely crossed-eyed teacher.

None of his pupils could stop staring at him.

Thx !
