Animaniacs (1993)

S1E78 Chairman of The Bored

The Warners find themselves trapped in a painfully dull encounter at a party with a monotone individual named Francis "Pip" Pumphandle, voiced by Ben Stein. As he drones on with a never-ending, one-sided monologue, the siblings endure what feels like the most excruciatingly tedious conversation of their lives. Their attempts to escape the mind-numbing chatter lead to a series of comedic moments as they grapple with the overwhelming boredom inflicted by Pip’s relentless storytelling.
