Kelsey Grammer on Modern Family
Steve Levitan and Christopher Lloyd worked with Grammer on Frasier and Back To You, so this proposed reunion feels fairly legitimate. Normally Grammer plays the stuck-up conservative — and why try to fix that? Cast him as Jay’s college roommate, a born-again with his eyes on Gloria...

Not bad. How about he play Dede's new [Canadian]husband who visits the family with the intent of helping DeDe show up Jay+Gloria but winds up being more attracted to Gloria than any of the others expected? Kelsey definitely could pull off chemistry with Shelley Long+ has enough acting chops to do a somewhat believable Quebequois accent. Now if Joaquin Delgado[Benjamin Bratt] joined them, things could could get quite interesting!
