A penguin meets a man in a wheelchair. The penguin says:
"Greetings and salutations, sir. Pray tell, what is the purpose of your mobile aluminium gizmo?"
The man in wheelchair answers:
"Well, it seems like I've got a couple of useless limbs."
The penguin says, with much stupefaction:
"Did you say useless limbs?"
He flaps his penguin wings, sits himself in the knee of the man in wheelchair and says smiling:
"Birds of a feather."
