Go on then 
A man in the office chuckling to himself when a colleague comes in and asks what is so funny…
‘I made a rather embarrassing Freudian slip this morning’, he replies.
‘What’s a Freudian slip’ asks the rather dim colleague.
‘Well, I was queuing for my train ticket this morning when I noticed that the girl serving behind the counter had enormous breasts.
When I got to the front of the queue to be served I was a little flustered and instead of asking for a ticket to tooting, I asked for a ticket to titting. You see, that’s a Freudian slip when you are thinking of something else and say the wrong thing’.
‘Oh I see’ says the colleague.
The next day (somewhat predictably), it was the dim colleague sitting in the office laughing to himself and the other worker who has to ask him what is so funny.
‘Well, you know you told me about that Freudian slip thing yesterday? I had one myself this morning’.
‘What happened?’ asked the startled man.
‘Well, I was sitting having breakfast with the Mrs. this morning and instead of asking her to pass the milk I said
‘you’ve ruined my whole life you fat ugly bitch.’’
