Annabeth: Percy is late again...
Jason: HOW DID THIS HAPPEN? I called him at eight this morning and pretended it was eleven
Piper: I printed out that fake schedule for him, saying that we were starting at nine instead of noon...
Leo: I set his clock to say AM when it's really PM
Annabeth: Oh gods, we may have overdone it.
*Percy bursts through the door*
Percy: WHAT THE HELL TIME IS IT?!
