A penguin drives to a walrus mechanic, because he is experiencing car trouble.
while the car is in the shop, he takes a walk to a nearby ice cream shop. he orders vanilla.
since he is a penguin, and has stiff wings, instead of arms and hands, he makes a mess and gets ice cream all over his face.
he get's back to the shop to pick up his car,
and the walrus has just completed the diagnosis.
he says to the penguin, "it looks like you blew a seal"
and the penguin says, "oh, no, that's just ice cream."
