Seriously now

Every time I have a spare, silent moment inside my head, this pops in! It's driving me crazy! This song is currently looping around on my computer because when it isn't playing then I'm singing it in my head.
My mother was humming it this morning (probably because of the ever-playing loop on my computer), stopped, turned to me and said, "Why the hell am I singing David Cassidy? Why don't you have any taste in music?"
I tried to switch to a different song about an hour ago, but it was no use. I simply kept humming I think I love you under my breath, waiting for the song to be over so I could switch back to David Cassidy, may he rot in hell.
There are times when I can't even sit, lie or stand still while listening to it. I suddenly spring alive and have to dance to it. Sometimes I get really into it and sing at the top of my lungs. Then, there are times, like now, where I feel like crying because I can't shake this song for the life of me. I'm sure they play this song in hell. The beginning of this song gives me the motherfucking creeps, but before I can turn it, I'm already sucked into the chorus.
Seriously, though, fuck David Cassidy. I seriously hope he goes to hell. Fucking hippie Partridge bastard.
On a side note, the song seems to be driving my fish bugfuck crazy as well. Every now and again I'll turn my head to him and see Wayne Brady giving me the side-eye, so I put headphones on.
