I'm quite late to the Lucasarts P&C party, and I often end up playing the games with a guide because I don't like clicking / using items on everything and hoping for the best...
but in Day of the Tentacle getting the dentures was a really memorable moment, because in a spark of lunatic clairvoyance I immediately knew what I need to do for it. :D it was a good kind of crazy solution

Damn, you always pick out the most insane GAs!
My most memorable moment (or rather moments) was in Monkey Island 2 were I need to solve the hand sign puzzels. I solved it by pure chance. One year later I played it again AND again solved it by pure chance. Only alot of years later I played it again and figured it out, but I still cant believe I somehow managed it two times to get around there by chance without knowing what to do.

Cool! Thanks for the great contribution. 🐵

Not my most memorable moment; just a scene I enjoy and think about often:

View attached image.

It was in Milkmaid of the Milkyway when the cow died.
.......................HEAVY SPOILER !! ^^^^^^^^^^^^^^^^^^

When the protagonist plays the music and the ghost with a saxophone started improvising in Blackwell Unbound.
When the protagonist meet her aunt again in Blackwell Epiphany.

Digging a grave in the original Monkey Island 2! Cracks me up anytime (the SE version somewhat loses the charm on that bit though)

Something from Zak McKraken (sp?) - loved that game. Possibly involving a yak.

Most memorable, or perhaps more accurately 'painfully burned into my memory', is that damned goat. That god-damned goat.

Broken Sword, for those who haven't felt the pain.

In ZakMcKracken when you go to Mars and in a closet there's the gas tank for the chainsaw you find in Maniac Mansion xD

Indiana Jones and the Last Crusade: Decapitating Indy and/or his father while being tied to the chairs.
And crossing the chasm near the end of the game :)

"Hi, I am Bobbin. Are you my mother?"

When I finally defeated the motherfucking goat in Broken Sword.
There were no guides online back then, and as a kid I thought calling the helpline could help. They could in fact NOT help. I had no idea what a helpline was back then. To my excuse I was like.. 7 or 8? :')

There's a reason this has it's own wiki-page; https://en.wikipedia.org/wiki/The_Goat_Puzzle

The scene near the end of Grim Fandango with Manny being super vengeful and all the flowers. Played that game when I was ten or so, that scene definitely left an impression on my tiny little mind.

Use pig on door in Simon the sorcerer.......

The giant monkey mech from... I think it was Escape from Monkey Island...

Thank you for the GA :)

Key or region-restricted gift?

Getting trapped in Myst because I made a wrong choice on which brother to save.

I'm a huge fan of Monkey Island, but I guess the most memorable and unique point n click I've ever played was Grim Fandango. Got it as a kid and the art and themes are incredible.

Besides Monkey Island games, I had a lot of fun with The Longest Journey and Deponia series.
Most memorable... probably beating the wizard with a calculator in The Longest Journey.

Since Monkey Island was THE first game I ever played...
Cognition: An Erica Reed Thriller - absolutely loved it!

"When I'm on the road, I'm indestructible..." [wheel falls out]

Conquests of the Longbow when I stumbled across Maid Marian in the forest.

Beat me to it: I was hoping for first giveaway :D

I was caught pleasantly surprised when I got the first, of many, “trophies of cowardice” in Justin Wack and the Big Time Hack. Granted it’s probably not the most memorable moment, but it was a fairly-recent memorable moment that I think is worth mentioning.

A fine choice!
