Theoretically and Realistically

A son asks his dad the difference between "theoretically" and "realistically". Dad says that hard but I have and idea. Ask mum if she would sleep with the milk man for £1 million. Mum says yes. Dad says now ask your sister if she would sleep with the newspaper boy for £2 million. Sister says yes.

Well there you go son, that's your answer Theoretically we are sitting on £3 million quid but realistically we are living with 2 slags!

My friend that is a fucking gem

That is excellent
