From Will & Grace Season 1 Episode 13, "The Unsinkable Mommy Adler": Grace's visiting mom, Bobbi Adler, a would-be star whose propensity for breaking out into show tunes and impressions dismays her daughter - and delights Will, Jack and Karen - wreaks havoc by suggesting Will and Grace wed, despite their sexual differences.

When Will winces at the fantasy of committing to anyone who needs to be the star of a relationship, Grace realizes she's more of a chip off the old block than she imagined. Meanwhile, Karen faces a pregnancy scare.
