Things I just don't understand

You've all seen them and likely didn't give them a second's thought.  But seeing a "This Car Climbed Mt. Washington" bumper sticker recently got me thinking, there are just some things that no matter how hard you try I would just not understand.  Interestingly, as much as I don't understand it now, that doesn't necessarily mean that my opinions can't change.  Case in point:  I've been training for my first marathon the past 3 months and that would have been on my list 5 years ago, but at this point in my life running has become a big part of who I am. Here's the rest of the list I could brainstorm (in no particular order).  What would you add or remove from this?

• Automatic transmissions in sports cars (even if transmissions are technically faster these days, the point of having a sports car is to have fun, and having fun requires a clutch and a shifter)
• Rick Santorum - Need I say more?
• Anybody still using a blackberry by choice over an iPhone, Droid, or Windows phone
• Pennies - At this point you can't buy anything for less than a nickel, so why bother?
• Drinking crap beer when much better stuff is available for essentially the same price (I'm looking at you Mr. Bud Light drinker)
• The Washington Post social reader app on Facebook - requiring users to use/install your app seems rather unsocial, no?
• Eating beef well done - I can understand and appreciate those who are vegetarian, but if you choose to eat beef and purposely overcook it that is just a shame
• Why NPR has yet to figure out some kind of subscription model so that those who donate (like myself) don't have to listen to the unbelievably annoying pledge weeks
• WWF Wrestling
• Nascar
