Eh, it's just property and nobody was hurt so I have no guilt about making a joke or worry about whether or not someone thinks its funny. If the truck belonged to someone here, or someone I knew, clearly I wouldn't have been insensitive. I'm not worried about being PC, poorly timed and tasteless is more my style. Some people like my humor, some don't. We can agree to disagree, it wasn't meant to insult anyone. Considering the audience here, I'm pretty sure most people have thick skin.
Making a joke about swift trucks causing accidents may not be funny, but it's not against the rules nor is it directly offensive. If you drive for Swift and you cause accidents, own up to it. If you don't, then it doesn't apply to you and you have no reason to be offended.
It's not my problem you've heard the joke 9000 times and don't think it's funny. Don't like my humor? Don't read my post. What's the big deal? Who really gets that upset about someone making a joke about their carrier? This is trucking, that's a daily occurrence. (Especially if you drive for Swift.)
And while I have no desire to sit at the "cool kids table" as you make reference to, it is clear that you are an established group of friends here and while I don't need to feel cool, I've only made an attempt to meet and talk with some new people who can relate to what I do and encounter at work. But shunning someone for making a lame Swift joke kind of makes it seem like you're keeping track of the "cool kids table," hun. It's not my style nor has it ever been my intention to make people feel bad about themselves or what they do from day to day.
