It's always a surprise when no one mentions this famous comedy team.

Both have been linked to other actors as comedy teams but came together on the big screen a number of times.

Their comic timing was honed so well on television. When they were together it was pure comic genius.

And their genius was at its best with "The Private Eyes."

Don Knotts and Tim Conway play inept police detectives for Scotland Yard in this 1981 spoof of Sherlock Holmes.

Conway (Dr. Tart) and Knotts (Inspector Winship) are summoned to a mansion where the murder of Lord and Lady Morley has taken place. Each servant has a motive and it is up to the comedic duo to find the killer before they become the next victims.

Yes, some of the gags are tired and silly, but I dare anyone not to crack a smile when Conway gets a mouthful of peaches while Knotts is delivering one of his many hot-aired soliloquies.

Other scenes, such as one where Conway zips his pants up when the mysterious figure in the black hood is revealed and another where Knotts and Conway find dead servants with rhyming notes from the killer, are a riot.

The movie was written by Conway and John Myhers and is rumored to have taken only two days. And while Conway has admitted the film is light on plot, many of the gags were improvised on the set.

These veterans were able to build from each other and construct a funny murder mystery. Their routines recall Abbott and Costello but definitely their own.

Knotts plays the know-it-all but inept investigator, constantly acting as if he knows how to be a detective. Conway plays his dimwitted sidekick who can't stop talking about a half-man, half-pig creature known as the "Wookalore."

Then there is the supporting cast of the servants. Justin the butler is played by Bernard Fox. The talented character actor has appeared in several television shows, movies and animated films. One of the oddest facts about his career is his appearance the 1997 film "Titanic" as well as the 1958 Titanic movie, "A Night to Remember."

But Fox's comic timing is on with this film. The butler who was almost hanged for killing all 17 of his dead wife's lovers was a perfect match for his dry, English wit.

If you are a fan of Conway and Knotts, then you will love this gem. You might have to be a bit of a bargain hunter, 'cause while this baby just recently got released on DVD, I have yet to see it on the shelves anywhere.

But keep looking, it's worth adding to anyone's home movie collection for a Saturday afternoon.
