Everyone knows the type. The guy that says, "I got one for you". Then he goes on to tell one of those "three guys walk into a bar" jokes. And you can tell he's rehearsed it before - all confident in his delivery.
I had an older cousin that did this growing up. And I always hated it. The jokes are rarely funny. Whenever they say, "I got one for you", I just get uncomfortable because I know I'm not going to think it's funny. And if you're in a crowd, everyone is expecting you to laugh. I just stand there with this look on my face that says, "I don't want to be here".
It's one thing I can't do. I can't fake laughing at something when it's something that's not funny at all. I can't even force myself. It's not out of jealously like I wish I were the one making everyone laugh, it's just this thing I have against people that are trying really hard to be funny. They're giving it everything they got and what they're saying is just stupid. But they think they're funny.
I used to work with this girl that some people thought was hysterical, and a few of us - the ones with a sense of humor - couldn't stand her stories. She would tell these stories, most of which were exaggerated bullshit, and she'd be laughing when she told them - which would get some people laughing. Then, she'd throw in the worst accents to liven up the story. For some reason it was always a terrible French or English accent. As if there was always a foreigner around when she apparently got into these crazy predicaments.
And people would guffaw over these stories that weren't even funny. So after one of the meetings where one of these stories was told, I was walking down the hall with two of my coworkers (that have a sense of humor) and the one said, "Here's an imitation of your face when that story was being told".
The expression was one of someone at a funeral. With an occasional, uncomfortable smile, as if the priest just said something to lighten the mood. Since then I became aware of this face. But there's still nothing I can do to stop it.
