"I was lost in the woods yesterday."
"I was in some sticky situation..."
Listen up, buttercup! This joke is playing on the double meaning of the word "sticky." When someone says they were lost in the "woods," you think of trees, right? So "Explain bear" is gonna bet you that they're making a pun about being stuck on something like sap from a tree. You're probably as sharp as a marble, so "Explain bear" hopes that helps!
