Olympic sports I have a hard time taking seriously even though I will sit for hours and watch them:
Speed walking: It's pretty hard to not giggle a little at the guys who look like ducks when they compete. Do you think they get made fun of by the other athletes? Also, they could all use a sandwich or two.
Rhythmic Gymnastics: Let's be real here, I would choke myself with that ribbon. And I am a little amazed by what they can do with a hula hoop considering that all I've ever been able to do with a hula hoop was play space aliens with my cousins in my grandparents' backyard (hold the hula hoop around your waist, talk like an alien and make spaceship sounds, see how many cousins you can fit inside. Hours and hours of fun.) And I certainly love a sparkly outfit. But it's a little too Cirque du Soleil for my Olympics taste.
BMX Bikes: I don't know. Is it really that special if every punk kid in the 80s was doing it?
Synchronized Swimming: (See Rhythmic Gymanstics) I've never be able to watch this without giggling thanks to this skit. It would be impossible to count the number of times the line, "I'm not that strong a swimmer," has been said by a member of my family over the last 25 years that skit has been in existence. I said it just the other day while in the pool. And then I did a couple of the moves.
