Mayor Mustachio

Mayor Mustachio is the "fake mayor of Seattle" who presents Sam with the Fat Cake World Headquarters tour voucher in the episode iToe Fat Cakes. He bears a strong resemblance to the Monopoly board game's mascot Rich Uncle Pennybags and was played by Spencer.

To congratulate Sam for going ten whole days without getting into trouble, the iCarly gang opt to reward her with a trip to the Fat Cake World Headquarters in Canada. Unable to get the real Mayor of Seattle to present the prize to Sam on the iCarly webcast, Spencer dresses up as Mayor Mustachio and hands the Fat Cake factory "golden ticket" to Sam instead.

Upon receiving the coupon, Sam screams disbelievingly, "Shut up!" and Mayor Mustachio responds, "We shall not shut up!" He then complains that his "mayor trousers are too tight in the crotch" and proceeds to adjust his pants live on the webcast while Sam, Freddie, and Carly look on in bemusement.
