Weasel is an aircraft pilot, with I.R. as his co-pilot. Their job is to bring passengers upstream because of a dam, created by beavers, getting in the way. However, things go wrong when there’s too much weight aboard.
I.R. adopts a baby, but is soon given lessons in motherhood by Weasel. This episode had to be revised in 1999 to remove the letter “N” from I.R.’s helmet after a lawsuit from the University of Nebraska.
Serving a 99-year sentence at a correctional facility with I.R. Baboon, Weasel starts to feel concerned about the inhumane correctional devices that are set up on fellow prisoners.
Whilst in prison, Weasel explains his crime when he stalked I.R. Baboon as a subject for a wildlife study, which turns out to all be a bad weasel dream that Cow had.
Both Weasel and I.R. end up in hospital after a collision course. However, a slight mix-up in the operation room leads to both having the other’s brain. This episode was originally meant to be the series finale, but the show was renewed for a second season.
Weasel’s theory on monkeys typing Shakespeare goes wrong when almost every monkey involved walks out on him. However, he sees hope in the form of I.R. Baboon, who writes a book entitled “A Troo Storee”, despite the fact that it lowers peoples’ I.Q. level.
Weasel is famous cowboy working in a rodeo in which Baboon is a clown. Cow and Chicken’s teacher and her husband appear in this episode. Cow also makes a guest appearance.
Weasel and I.R. run one of the best hair salons around. However, the hair police (The Red Guy) soon has a look into this in an attempt to shut them down.
