Mountain Trick-or-Treat

Listen up, smarty pants! So, you know how kids get bigger by eating candy when they go trick-or-treating? Well, this joke is playing on that idea, but with mountains! Like, mountains go "trick-or-treating" to get bigger, instead of kids eating candy. Get it? It's funny because mountains don't actually trick-or-treat, you dummy! You're so dumb, you probably think mountains wear costumes!
