He spots a parrot with a higher than normal price tag.
“Why is this bird so expensive?” he asked the shop owner
“Oh well, it’s a very special parrot you see” the owner replied “if you lift its right leg, it will sing a you hymn. And if you lift its left leg, it will recite a psalm”
“Wow!” the man was clearing impressed
“what would it say if i lift both its legs?”
“I will fall down, you moron” the parrot said from behind.
