Al Harrington is the owner, president and CEO of Al Harrington's Wacky Waving Inflatable Arm-Flailing Tubeman Emporium and Warehouse', located off of Route 2 in Weekapaug, Rhode Island. The business specializes in sales of Wacky Waving Inflatable Arm-Flailing Tubemen.
In an advertisement he speaks at an incredibly fast rate and was described by Peter Griffin in the second Stewie Griffin: The Untold Story segment "Bango Was His Name Oh" as "in-your-face, but just in that friendly-annoying way".
He also appears in "The Former Life of Brian" this time selling 'Crudely-Painted Not-So-Funny Plywood Cut Out Folk Art', which he obtained as an unwanted result of a recent lawsuit. The art includes such favorites as "Sort-of Ben & Jerry's Looking Cow' and 'Fat Woman Bending Over Tending To Her Garden In Big Polka-Dotted Bloomers". He is selling them at his 'Wacky Waving Inflatable Arm-Flailing Tube-Man' Emporium and Warehouse along with his regular stock, and wishes to get rid of them quickly as they were a "tremendous" fire hazard.
In "Back to the Pilot", he is referred to by name when it is revealed what the Griffins actually do during a cutaway gag. Peter says his new boss is meaner than a shifty salesman, and after that setup, Brian drinks, Peter smokes, Lois applies makeup, and Stewie, Chris and Meg text. When Lois asks if Peter has enough time to smoke, Peter says that it's an Al Harrington gag, which is known to be a long joke.
Al advertises for a date in "The Book of Joe" as a "Short but handsome, slightly hairy, newly single salesman."
He is voiced by Executive Producer and writer Danny Smith.
