Went to a Garden Potty

S4 E20: In the aftermath of his parents' divorce, Will (Eric McCormack) salvages a beloved garden gnome - nicknamed "Squatsie" - and proudly plants the childhood relic in his apartment's community area until Grace (Debra Messing) accidentally delivers a coup de grace on the gnome's dome with a shovel. Elsewhere, Jack (Sean Hayes) consults his acting coach (guest star Eileen Brennan, "Private Benjamin") when he fears that his heterosexual role in a mattress commercial produced by Karen (Megan Mullally) will stereotype him for more meaningful gay acting gigs in the future. Tom Poston ("Newhart") also guest-stars.
