One early winter morning, an old Chassid was walking beside the canal when he saw a dog in the water trying hard to stay afloat. The old Chassid jumped in and after a struggle managed to bring it out alive.
A passer by saw this and said, "That was so very brave of you! Are you a vet?"
The old Chassid replied, "Of course I'm a vet! I'm a freezing cold as vell!"
