the Ian/Teri head-turn is very comic and many of the other nominations in this thread are interesting. But I ask if they are they truly epic? Few are in my opinion.
I suppose it all comes down to a subjective definition of the term 'epic'. Personally, funny moments are quite epic for me, but might not be for others.
But if we are talking about a truly 'epic' moment, it is impossible to look past the watermelon slingshot!
