Zeebo is a fictional character on Nickelodeon in an episode of iCarly in 2008 when he ruins the iCarly TV Show.
He says "I'm Zeebo" and he hits Carly & Sam and then he does the same thing again and refuse to quit it and then says "Kaboom" while hitting them. Sam later grabs a microphone and beats him up. The man in the costume was a middle aged man who appeared in 4 episodes of Full House.
Amber Tate appears and then Zeebo says "I'm Zeebo." he then sings his own original song (rip off to Barney's i love you song) and then the music ends before it finishes.
In the end
Zeebo: But Michelle, why do you have two dates to the prom without even asking?
Amber Tate: Dad, Luke is so sweet, but Brandon is so hot.
Zeebo: Oh Noodles (as he hits Amber Tate)
Carly, Sam, Freddie, and Spencer: Lame (they then turn off the tv).
