Day of the Tentacle
This is one of my favorite games from my childhood. If you haven't ever played it, you owe it to yourself to purchase the remastered version [1] and play it through (it's only $3.79). It's incredibly entertaining and witty. I doubt this game will ever get stale.<p>[1]: <a href="https://www.gog.com/game/day_of_the_tentacle_remastered" rel="nofollow">https://www.gog.com/game/day_of_the_tentacle_remastered</a>
