Dale and Kelly are ready to have some fun with the keg. Again, Riley is not invited.

Kelly: (To herself) Can't she take a hint? No one wants you here, witch, so just go away.

Ignoring Riley, Dale helps Kelly do a keg stand, but at that instant his phone starts ringing, right after Riley pulled out hers, what a coincidence.

Kelly: Do you have to get that?

Dale: I'm sorry, it might be from home.

From home, yeah right, Dale has talked to his whole family earlier. Kelly's sure Riley made that call just to annoy her.

 Dale: Hello? Hello? 

(Riley discreetly runs away).

Dale: There was no one on the line, must have been a wrong number.

Kelly: (From the dining room) Wrong number, my a**!

Dale already checked the call number, yep, it was Riley who called him just to interrupt the keg stand.

Dale: (to himself) Dammit, Riley, when will you leave us alone? Ah, I hope Kelly isn't mad at me.
