I heard about Brain Donor's and thought that it was a joke that someone told me. I didn't even think that this existed. Man! What a comedic-hammering I got when I saw this. This has to be up there as one of the slap stick funniest of all-time. If it's not something is truly wrong with our critic-rating system. These guys, who i wasn't aware of except Turturro from Miami Vice and William Friedkin's "To Live And Die In L.A." and those certainly weren't comedy. So I had no reference for him to gage in a comedy. These other two Bob Nelson and Mel Smith where outstanding! Thy were unbelievably funnier than other comedies that were in the theater then. I am just astounded that there are no reported awards for these guys in this film. From all the other stuff that wins and for this not a 'wink' 'nod' or 'whisper' to speak of. Dennis Dugan has a great sense about him in comedy story telling. And for all I can remember, of seeing his movies, he always has, hence : 'Problem Child' etc.
I was glad to see that this is now out on DVD. As before I was wearing out the VHS that I had with it playing so much. Yet it has been years since I have had the enjoyment of this.
For a real comedy-face slapping good time, I recommend these guys to only those with a sense of humor. Those without need not apply. Now this is one that you have a sequel for or two or three.
Ten out of a comedy ten (*****)
