"'Cuz You Had a Bad day, you...?"

What comes next in this song? I've never been able to figure it out. People should really enunciate more when they sing, or refrain (punny) from singing, like me.

Anyways, today has been kind of a crappy day. But something happened that made me love life! Do you want to know what it is?
I took a practice test for my Chemistry finals coming up... and I got a 12/14!!!! Woooo hooooo!
