ya, but alan alda and john lennon together, john probably playing some british doctor that is stopping through, and yoko as some korean that he becomes entangled with. i think it wouldve been worth it and their writers would make it one of the best. it would probably be better in one of the first 3 seasons when Trapper was there, cause those are the funniest seasons ever.
for all we know they probably offered and he said he wouldnt do it cause it would mean he'd have to cut his hair.
