A bird that lays down !
Because they grow the olives inside, away from the birds and the bees.

Because they always fly over everyone's head.
The rest are hunting peckers.
Their peckers are on their heads.
A: Fell through the cracks.
Because he doesn't like looking down on the unemployed. First to ever post this joke here, yay!
