A man and a whale are sitting in a bar

This is one of my favorite jokes. I hope it hasn't been posted; sorry if it's a repost!

A man walks into a bar an noticed a really sad looking fellow sitting with a beluga whale in a corner booth. The man walks up to the bartender and orders a drink. When the bartender returns, the man asks him, "what's up with that guy and the whale?" The bartender answers, "that's Tim, he has quite a sad story. If you go and talk to him I'm sure he'll tell you about it."
So the man orders Tim and the whale a drink and takes it over to them. "Hi, I saw you're looking pretty down and I thought this might cheer you up", he says. Tim gratefully accepts the drink and the man places the other one in front of the whale who just stares at him blankly. Tim asks him to have a seat and starts talking about what's been going on in his life lately. "Well, I thought everything was going great for me. I had a great job doing something I love, a beautiful wife, house, you know? The whole american dream! But over the last few months it's slowly started falling apart. My company had a bad year and started downsizing, and I lost my job. The financial stress has put pressure on my marriage and my wife informed me a few weeks ago that she is leaving me. She's taking everything, even the dog."
The man really feels sorry for Tim and tries to comfort him as best he can. He even buys him another drink. After a little while he can't ignore the whale anymore. He turns to him and asks, "so what's your story?"
The whale replies, "OOOOOAAHAAHHGHHOOOOOOOAAAAOOOAOAOAHHH"
