Weezer - Why bother

I know I should get next to you
You've got a look that makes me think you're cool
But it's just sexual attraction
Not somethin' real so I'd rather keep wackin'
Why bother? it's gonna hurt me
It's gonna kill when you desert me
This happened to me twice before
It won't happen to me anymore
I've known a lot of girls before
What's the harm in knowin' one more?
Maybe we could even get together
Maybe you could break my heart next summer
It's a crying shame I'm all alone
Not with you, nor her, nor anyone
Won't you knock me on my head
Crack it open let me out of here
