Will & Grace: Season 8, Episode 8

8 - 8: Swish Out of Water

Grace finds it impossible to put up with her mother Bobbi's (guest star Debbie Reynolds) constant nitpicking, so Jack takes it upon himself to help her because, according to him, no one knows how to be a good daughter better than a gay son. Jack subjects her to a barrage of Bobbi-esque insults until Grace finally learns what her mother really means underneath her harsh words. Meanwhile, Will's (Eric McCormack) first case at the Coalition for Justice is about tenants' rights, and the slumlord turns out to be none other than Karen.
