Just finished watching the Columbo episode "Lovely but Lethal" and discovered that Gino Conforti who played Felipe on Three's Company was in this episode and played a character named Ferdy. I never would've recognized him without that accent!

I have a similar story about him. I was watching Get Smart when a "hey, he looks vaguely familiar" guy popped up. I got the actors name from the credits, looked him up, and it was "Felipe".

I also saw Gino on the Mary Tyler Moore show and the Waltons.

Both episodes were very early episodes in those series.

Yeah I saw Gino in an episode of Small Wonder, real funny he was playing a maitre'd in a French restaurant and talking with a French accent when later on he starts talking with his regular voice.

edit: he wa also in an episode of CHiP's as a banker.
