Charles Clay, Lt. Columbo and others in “Unfinished Business”

Yes sir, I guess that's all true and that guard, he certainly remembers what time you left just like I told you he did. But that's exactly what's been bothering me right from the beginning-- time. Ever since I saw that beautiful watch of yours. Time. Why would you check with the guard when you were leaving the island, the time? He's got a drugstore watch. Unless you wanted to make certain when you were leaving he would remember...

The time.
