Bad Italian Food is NOT funny

What is it with the Olive Garden commercials? How come everyone is so damn happy and how come everyone laughs hysterically at everything everyone says. Sample dialogue:

Suprisingly Non-Obese Male Customer 1: Oh boy, it's all you can eat pasta tonight. I'd like another bowl with marinara sauce.
Annoying Wife 1: Haven't you had enough?
Surprisingly Non-Obese Male Customer 1: No way!
(Laughter all around the table)

OK, clearly not funny. Also, nobody can be that happy while shoving bad quasi-Italian food down their gullets. Here's a more realistic scenario for that commercial:

Male Customer 1: This food sucks, but I want to get my money's worth, so I'm gonna have another bowl.
Annoying wife: Hey, fatso, maybe you should lay off the complex carbs and have a salad instead.
Male Customer 1: Shut up and leave me alone. I hate you.

Now THAT's much better.
