Pip was a minor character voiced by Ben Stein.
He appears in "Chairman of the Bored", and bores the Warners with his long, one-sided conversation. He later appeared in Wakko's Wish as the Good Fairy/Desire Fulfillment Fascilitator. If one were to shake hands with him, he would ramble on, and no matter what the character tried (be it pulling or using a crowbar) he or she would not be able to let go of Pip's hand. No matter what a person did, they would never be able to stop him talking, much less get rid of him: they would have to wait for him to finish, and when he did finish for the Warners, they realized they missed his constant talking.
He appears to be a parody of Ben Stein, his voice actor.
