A pea, a lemon, and a potato were leaving a bar at the top of a very steep hill after a long night.

The pea, feeling quite energetic, shouted, “Lads! We’re all round — let’s just roll home!” and immediately shot down the hill.

The lemon wobbled after him, but his oval shape made him list violently from side to side, and he ended up tumbling end-over-end into a hedge.

The potato just stood there. The pea, picking himself up at the bottom, called back: “Oi, Spud! Why aren’t you rolling?”

The potato shrugged: “Because I’m a potato. Potatoes don’t roll.”

“Why not?” yelled the pea.

“Because we just sit there. We can’t even.”
