Dum-da-dum-dum-dummmmb! The Three Stooges parody Dragnet in "Blunder Boys". How they were able to get through college is an even bigger mystery.

In comedy, there is a variation on a joke known as "The triple". The Stooges employ this several times in the film, with Shemp delivering the punch line.
