One day at a meat shop a dog walks in and the butcher shoos him away. About 5 minutes later he comes back with $10 and a note saying "2lbs of steak" surprised the butcher reluctantly takes the money and hands him a bag with the meat.
As the dog left the butcher closed down the shop and decided to follow it. The dog gets to the bus stop and waits. A few buses pass and the dog ignores them still not eating the meat. Finally bus 923 arrives and the dog pulls a ticket out of its collar, gives it to the driver and hops on.
The dog does this for about 3 more buses and the man follows him every time. The dog got off of the last bus and began to walk still not have eaten the meat. Finally the dog walks up to a house and sets the meat down.
The dog backs up and charges and slams into the door. He does this about twice. Finally a man opens the door and starts yelling at the dog calling him stupid and retarded.
The butcher finds this horrible so he talks to the man and says "STUPID?! This dog went to my shop, paid for meat and took it on a series of buses finding his way back home perfectly. HOW IS HE STUPID??!"
The man then replied saying "Yes, that's all great but he forgot the key the 3rd time this week!"
