"Night of the Lepus" (1972) - What is up with the first few years of the 70's ? Can we plan bad acid trips?? Here is a youtube link to the trailer from this one, if you can stand it then watch the whole flick......
"Monty Python's Holy Grail" (1975) - yes, it really must have been the drugs......This one you need to watch for its iconic throwback status - check out what formed your parents sense of humor! And watch out for Bunnies, i'm just say'n.
"Harvey" (1950) - Now after all that evil rabbitness, sit quietly, relax and watch the delightful Jimmy Stewart in one of his best roles. Don't question it or try to figure anything out. Just go with it and enjoy. An innocent sweet comedy with quiet mid-century sensibilities.
