Character mistake: Given how Monk is it seems unlikely he'd forget about being in a dumpster filled with garbage and be able to enjoy a birthday party, even if it's his own.
Mr. Monk and the Voodoo Curse - S8-E7

Mr. Monk's Favorite Show - S8-E1

Mr. Monk's Favorite Show - S8-E1
Continuity mistake: Near the end when Monk is doing his usual "Here's what happened" speech, he hands an envelope to the dad. A few minutes later he walks away from the dad, who still has the envelope in his hand. Immediately, the shot changes and Monk, who is not near the dad, has the envelope.
Mr. Monk Goes Camping - S8-E12
Audio problem: At the beginning of Season 8 Episode 12, the round analog dial clock on Monk's nightstand beeps like a battery operated digital travel clock would, and Monk looks over at it. But in Season 8 Episode 16 (at about 38 minutes), that very same clock has a bell type ring that one would expect of a wind up analog dial type clock. (00:01:00 - 00:38:00)
Answer: Notice also that in the opening credits scene when he is touching parking meters her also wipes his hand on his clothes each time he does it.
