S1·E4 Love! Valor! Deception!

Eddie entices Kirk to help him sneak into a party where Eddie hopes to interest a wealthy investor in his latest invention -- a belt made out of cured meat. Kirk agrees to help because Elizabeth will be there. However, Kirk's romantic hopes are ruined when he sees Elizabeth at the party with an older man. Kirk is angry because Elizabeth told him that she doesn't want to date anyone right now. Kirk returns home to Phoebe, who is baby-sitting Russell for the first time. Unfortunately, Russell's feet got stuck in the couch when he was jumping on it, and Sally had to help free him. However, Sally keeps what happened a secret. Finally, Kirk confronts Elizabeth about her date. Elizabeth tells Kirk that the man with whom he saw her was her boss, whose wife was also at the party. However, Elizabeth still doesn't agree to go on a date with Kirk.
