Taxi - Season 5 Episode 10

Latka and Simka introduce Elaine to a friend of theirs visiting from their country named Zifka. Zifka is a monk who has taken a vow of silence but during his vacation is allowed a week (every ten years) to experience all worldly pleasures. He and Elaine quickly fall in love (seemingly to Alex's dismay) but Zifka must resume his silence when his week ends right before he can tell Elaine exactly how he feels about her. Elaine is saddened but understanding, and lets Zifka go.
