I was snowboarding with my dad (who was skiing) and he pulled this.
Setup:
I didn't have enough speed to get past a flat area that we reached, and we were on our last run of the day. I had to unbuckle one of my boots and pushed myself to the slope. My dad was worried that we were running late and they would send ski patrol to guide us down. (We got on the lift last minute)
The joke:
dad: "what are you doing?"
me: "I was getting close to the wooded area (there was a fork) and I didn't want to run into a tree"
dad: "well hurry up and let's skedaddle ski-daddle"
I didn't get the joke until I was going back downhill, so he didn't hear how hard I groaned.
