Teaching joke :)

A new geography teacher comes to the classroom for a lesson and says:
– Today we’re going to talk about what a globe is.
The class replies in chorus:
– Fuck off, you old bitch!

The teacher broke into tears, ran out of the classroom and went to the school principal.
– Fellow, says the principal. – I will show you how to deal with our students….

After a while, the school principal enters the classroom and begins:
– Hi, little bastards!
– Hello, bald fucker!
– Today will be talking about how to put a condom on the globe.
– On the globe? – the class is surprised. – And what is a globe?
– And this is what we will start with…
