It’s a bit shorter than I usually post, but seeing that this morning I had to deal with a surly dog with a bad attitude (not mine), Here you go!
A blind man and his seeing eye dog are waiting to cross a road at some traffic lights when the dog cocks his leg up and pisses on the blind man’s trousers.
The blind man proceeds to get a dog biscuit out of his pocket to feed the dog.
A bystander says “excuse me sir, your dog just pissed on your leg and you are going to reward it with a biscuit?”
The blind man replies “I’m trying to work out which end is its head so I can kick it in the arse!”
