1) As soon as
Jimmy started playing that heavy-ass skull crusher shit through his airplane headphones his brains fucking spewed all over my goddamn shirt, so now I have to go out to Wal-Mart and buy a brand new one. But I think I'll keep the old one as a memento.
2) Dude I though
Brad was going to kick Jack's ass when that

3) I gave my girlfriend a skull crusher last night, so she took off
school today because she had a sore throat.
