A Vet

One early winter morning, Rabbi Bloom was walking beside the canal when he saw a dog in the water, trying hard to stay afloat. It looked so sad and exhausted that Rabbi Bloom jumped in, and after a struggle, managed to bring it out alive.
A passer-by who saw this remarked, “That was very brave of you! You must love animals; are you a vet?”
Rabbi Bloom replied, “And vhat did you expect? Of course I’m a–vet! I’m a–freezing cold as vell!”
