What is the name of this MONK episode? The one where the young man kills his girlfriend with a saw?

I think it's one of the earlier episodes in season 1. It's this episode where at the beginning of the episode, there's this young woman and young man (age: 20s) sunbathe in the sun outdoors, the young man kisses his girlfriend saying "I have a surprise for you! Close your eyes!". The man takes his girl by the hand and leads her into a garage filled with working tools and closes the doors, even the garage door. The girl is excited and still has her eyes closed. The man says "No peeking!". The man takes a chainsaw, turns on the motor, and surprises her hacking her to a bloody gruesome death. We only see the blood splattering on the windows of the garage door during the murder. What's the name of this MONK episode?
