Shermy and Charlie Brown struggle to stand on the ice in their skates. Shermy says,“Watch it!”
Shermy says,“Oops!” as he starts to fall. A shaky Charlie Brown says,“Careful!”
He falls down next to a fallen Shermy.
He sits up and says to a kneeling Shermy, “Let’s jump over barrels!”
I don’t get this one.
Think it’s referring to Barrel jumping, and the joke is that they prematurely think they’re ready to do a highly-skilled activity.
