To be honest with you, the song is hilarious. I mean, listen to the lyrics! Some examples:
'I just had sex / and it felt so good / a women let me put my penis inside of her'
'When I had the sex / man, my penis felt good / and I called my parents right after I was done'
'She could be my wife / That good? / The best thirty seconds of my life'
The song strikes me as a nerd's anthem really, or rather what society perceives as a nerd's dream. So basically it makes fun of the unpopular kid, but they do it oh so well. It's a funny song, but is it actually any good? Truthfully, I don't think I'd like it as much as I do without the video. My first reaction when I heard it was 'What the hell is this? Are they fucking serious?' Actually I didn't know what to think about it, but I gotta say it's actually kinda catchy. Don't think it's the song I'll be singing/humming in a public place though. Or I might just to annoy people.
