Jimbo Kern is the local gun nut of South Park and is also Stan's uncle. Jimbo runs the local gun shop, fought in Vietnam, and is an all round nut. We love 'em.
Jimbo: Hey Ned, look what I got you: a new voicebox! (Ned reaches for it, but Jimbo blocks it) You want it? You want it? Here you go!
Ned: (Irish accent) Jimbo, I can't thank you enough for the new voicebox! What in the devil is this, then?
Jimbo: Sorry, Ned. I must have picked up the irish model by mistake.
Ned: Oh, what a bloody pickle this is. Did you keep the receipt, then?
(A man walks in)
Man: Jimbo, Ned, come quick!
Jimbo: What's going on?
Man: They've found another Jakovasaur!
Stan: Uncle Jimbo, we don't drink beer.
Ned: Oh yeah that's right I don't think 8 year olds drink beer.
Kyle: I like chocolate milk.
Jimbo: Well, we'll be doin' plenty of drinkin' on this hunting trip. After all, hunting sober is like... fishing... sober.
