Re: Your "I just don't get it" list
Beer - it's just a beverage, I don't get the obsession some people have.
Golf - another obsession I don't get. The only fun part is driving the cart.
Harley-Davidson - they're just big and noisy. You're paying for name, not performance. So many Japanese bikes would kill a Harley.
Tom Brady - why does the sports media insist on making this guy a star? He doesn't make mistakes and puts up decent numbers, but really he's ridden the coattails of a great defense and coaching staff. The guy has a hard time just making the Pro Bowl, but announcers keep telling you he's the next Joe Montana. Looks more like the next Trent Dilfer to me.
Angelina Jolie - I'm sorry, she just doesn't have it.
Pink Floyd/Led Zeppelin/etc. - just don't get it, that's all.
People who won't learn other people's names - I'm not calling this forum out in particular because I see it everywhere. But every time I see something like Jimminez or Van Popple it makes me cringe. It's just a simple respect thing to get someone's name right.
