S4 E24: After Will (Eric McCormack) wins a portrait session at a charity auction, he takes Grace (Debra Messing) to pose for a notoriously eccentric celebrity photographer (Oscar-nominated guest star Glenn Close, "Fatal Attraction") but the unfocused shooter's bizarre methods ultimately produce a funky image that flatters Grace - and frightens Will. Meanwhile, Jack's (Sean Hayes) back with another performance act, and this time he employs magic tricks but regrets using Karen (Megan Mullally) as his assistant.
