I can't tell what movie contains what, but you father smells like eldarberries sounds like the exchange they had when they built the giant rabbit trying to get into the castle. The guards at the castle were exchanging insults with the guys on the ground. "Your mother was a hamster!" or "I fart in your general direction." LOL That was great stuff! I want to say I think you're right about it being in The Holy Grail.

I wish I could've caught this when it was in Chicago. I know I would've loved it! *G*
