I'm trying to find the episode of Monk where he and Trudy end up in a creamatorium and Monk is pouring the remains from one container to another to make them even. Can 당신 tell me which episode that is on?

The episode is Season 6 Episode 5 "Mr. Monk and the Birds and the Bees"!
(And btw, the woman he is with in that scene is his assitant Natalie, not Trudy!)

Hope this 답변 your question! :)

In The Birds and the Bees Monk accidentally upsets half a dozen urns in a crematorium, and with the help of Natalie he quickly clears everything up. But as he adds spilled ashes he wants them to be filled equally among all the urns. (Actually, if they hadn't been in a hurry he would have put each deceased person's ashes back neatly and individually.) This has nothing at all to do with Trudy.
