The Dumb Beaver is a Family Guy character who was indirectly victimized by one of Stewie Griffin's insults. While trying to guess who Peter won a round of golf with via an old raffle ticket in "The Juice Is Loose", Lois makes an incorrect guess and Stewie calls her a 'Dumb Beaver'. The scene cuts to a none-too-bright beaver. The beaver makes a few more cameos, retreating when O.J. Simpson shows up.
In "Brian the Closer", he makes a joke about Brian helping with building a dam after he gets new teeth following a fight with Peter. Peter acknowledges the beaver's occasional contributions to the show.
The Beaver is voiced by writer and producer Alec Sulkin.
- A 'beaver' is a slang term for a woman's private area.
