They just wing it.
Time's fun when you're having flies.
Sorry for a post that's not a joke but I'm interested. Here's one from where I am. These two ducks are flying over Ballymena. The first one says, "quack quack" and the second one says, "slow down! I'm coming as quack as I cyan."
A walk.
It has legs, but doesn't walk, beak, but it doesn't bite and wings, but it doesn't fly. What is it? -A dead crow
It broke the law of gravity!
It chickened out.
That's my buoy!
