Anyone know who does this song?

[starseeker]

It's a parody of All Star by Smashmouth. The only lines I heard were

'Last night I was surfing on the internet,
Speeding through cyberspace,
I was in a chatroom up in an adult site
Oh my God, I recognised that face

Granpa he's a porn star...'

If anyone knows what this song is, could they tell me.

[Kirobaito]

That is a Weird Al Yankovic song entitled "Grandpa's a Porn Star".
