The Yes Guy

The Yes Guy possibly named Frank Nelson Type, but normally referred to as That Annoying Guy Who Always Says Ye-e-e-es, and sometimes referred to as the obnoxious yes guy, by Homer, is a character known for bellowing “Ye-e-e-es?!” in a rising inflection, and appears to be highly eccentric in both his speech and appearance, voiced by Dan Castellaneta. He says 'Yeeeeees?!' all the time because he had a stroke.

Appearances
During his first appearance, in “Mayored to the Mob,” Homer asks “Why do you talk like that?”; Yes-Guy’s response was “I had a strooooooke!” He also made an appearance in Homer vs. Dignity of Season Twelve. During "The Great Louse Detective", he enjoys Marge Simpson's hair rubbing upon his buttocks. He is often seen working at Costington's department store, in which both he and Costington are apparently on good terms with. He is juror number twelve of the Springfield Panel of Jury ("The Monkey Suit"). During "The Lastest Gun in the West", he gives Bart Simpson some free ice cream. He's very very funny in Apu's eyes.

Creation
The Yes Guy is a tribute to character actor Frank Nelson, and his familiar persona on The Jack Benny Program (and modified for appearances on I Love Lucy, The Flintstones, Sanford and Son, and others). Nelson's trademark greeting was a loud, drawn-out “Yeeeeesss?!” This was often augmented with a sarcastic "OoOOOoooh!" Originally, this character could be found in a variety of occupations, usually as a salesman or waiter, which Jack Benny or others might be patronizing, and his Simpsonian counterpart is equally omnipresent.

Variations
A Brazilian version of the Yes Guy can be seen in the episode "Blame It on Lisa," uttering Portuguese variation of the catchphrase: "Si-i-i-i-m"?!

Physical Traits
" The Yes-Guy shares several physical characteristics with his real-life inspiration, Frank Nelson: he can be described as a rather squat, stocky man with a moustache, and black hair receding into a widow’s peak...
