Tom Lair (voiced by Byrne Offutt) is Irma's overweight police officer father. He is a party animal and a sports fan who hates when the garage gets dirty and has little patience for fussy people. He can be nice and mean towards Irma at times. He is very strict and expects his children to be clean well-behaved and get good grades. Tom is an expert in interrogatories, as Irma puts it. He is a little more aware of Chris' bad behavior than his wife. He is seen doing patrol duty in "Z is for Zenith" where he is almost killed by Cedric.
