Really bad LSD. film.

[Svengoolie 3]

I think this was used for a clip in "'cheech and  chong's it csame from Hollywood" movie. There was a segment  comparing taking LSD to I think riding a cosmic chicken and had a matted on bit of a poorly drawn chicken cartoon spinning around.

A all of mine who used to do acid might want to see it.
