I am having trouble remembering which episode it was where Grace was asking Karen for help and Karen starts to sing the first few lines of the Trolley Song "Clang CLang CLang went the trolley, ding ding ding went the bell, zing ZING--" and then Grace interrupted her. Could anyone out there tell me which episode that is? Thanks.

"Where There's a Will, There's No Way"
