A horse, dog and cat go into a bar.

The horse buys 3 pints for each of them.

After 20 mins the dog goes to the bar and buys 3 drinks for them all.

20 mins later the horse goes to the bar and buys 3 pints.
The barman said - "why are you buying - surely its the cat's round?"

The horse replied -
"it's what happens when you date a tight p u s s y!"

Purrrrrrrr

i remember something similar when i was younger, but it was an ostrich and a cat:
man walks into a pub with an ostrich and a cat and orders 3 pints,
10 mins later, ostrich orders 3 pints, this carries on until closing time, when the landlord calls the guy over

"what's the situation? how come you and the ostrich have been getting the drinks in and not the cat?"

man replies:
"well on my way to the pub i found a genie lamp so i rubbed it and the genie granted me one wish, so i said i wished i could have a bird with long legs and a tight ***** with me tonight"
