This song isn't meant to be taken seriously. It's just for S's&G's. If you listen to live performances, they tend to say a lot of funny, immature things. During a performance of What's My Age Again, after the second verse one of them shouted out "It's the slow, pretty part" you may not see the humor in that, but I do. They were making fun of their own song to get some laughs. After that performance, they had a humorous conversation about dog semen. So give 'em a break if you think they are all sick in the head for this song. I know of two other funny songs by them: The Blow Job Song and When You F***ed Grandpa.
