I don't remember George Carlin in that film, but he was in another excellent one called Bill and Ted's Excellent Adventure and the equally non-heinous Bill and Ted's Bogus Journey.
Hmmm. I may be mixing this up with another movie, but I thought I remembered that George Carlin appeared as a minor character, who at the end morphs into an alien and beams up to the mothership.
Psst, I already mentioned Naked Gun, along with several other Leslie Neilson movies. ;p But i suppose it does deserve a second recomendation for it's greatness.
I am unsure if anyone has mentioned them, but the Bill and Ted series always brings a smile to my face
I am saddened to see that two of my favorite comedy's have not so far made the list. This must be rectified! I give you. Good Morning Vietnam and Trekkies.
