Is this a sign of insanity?

I have been studying for finals all night and now I am starting to respond to commercials.
Commercial: What would you do for love this Christmas?
Me: Would you kill a man?

Commercial: ...Oh what fun it is to ride in a one horse open sleigh.
Me: I hope you fall out and die!

Commercial: (talking about the OC) It will take one friend to make it a holiday they won't soon forget.
Me: One of them is really an alien from tralfamadore!
