'Columbo' still confuses those who watch

No matter the case Columbo (Peter Falk) is working on, he still manages to confuses those around. That part of the show still holds up.
- He knows the killer early and we get to see him solve it with that knowledge. But, the killer thinks he does not know and is a bumbling fool.
- The show ran from 1971-2003, in some form or another. See IMBD.
​- Yes, he was a slob, had a classic old car and a hound dog. He smoked a cigar. 
- He had only one functioning eye.
- The show is actually quite funny. 
- The show was shot all over Hollywood and surrounding picturesque settings. A nice backdrop to the crimes.
- Some of the guest stars are really bad actors, yet some are and were major stars.
- "One more thing" is just as irritating to hear whole watching as it was originally.
- He was the first person nominated for an Oscar and Emmy in the same year (1962) ...however, not for "Columbo." That was not conceived yet. See METV here. "Columbo" currently airs on METV.
- His first name is Frank.
​- His wife is never seen or heard.
