I think #6 is Brimmer (can't remmember his first name, but it's Robert Culp in Death Lends a Hand), and I think #8 is Alex Benedict (John Cassavetes in Etude in Black.)
Great Gregg!! You got them right!!
um...the reason you can't remember Brimmer's first name is because he didn't have one!!
Oh dear!! I hope this doesn't start another "What Was Columbo's First Name" thread!!!!
And yup! That was my Johnny talking in #8.
#6 is when Columbo is eating lunch in brimmer's office, some sort of a fish dish. It is one of my favorite episodes. Of course, the real quote comes at the end of the show .... 'you take a potato, and you stuff it in the tail pipe. Doesn't do any damage, but the car won't start.'
