I found some bits funny. Jensen Ackles delivery of the explanation why he was scared to go up to the room on the 4th floor was beautifully timed.

But other bits didn't amuse me as much as I'm sure they were meant to. possibly because I'm not so much into full on slapstick. For instance, I love Blackadder but I'm not into Mr Bean at all. I think that I like my humour wordy, witty and/or ironic. But that's just me.
