Sweet and Sour Charity is the eighteenth episode of the second season and the 40th overall.
After winning a call-in radio contest for prized Joni Mitchell concert tickets, Grace vows to reciprocate and volunteers her time to charity, but when she recruits Will to join her at a community center, she quickly begs off her commitment when it conflicts with her busy social calendar. Meanwhile, Karen and Jack don't escape either from Grace's newfound charity which forces Karen to rifle through her closet -- and allows Jack to accidentally donate a pair of Karen's most-prized shoes.
