And here are some spoofs:

Uh oh, they forgot to look before they crossed.

Dr Who



Abbey Troopers doing YMCA. Hmmm....

Gah. Please guys, put your clothes on.



With Christian monks.



With Tibetan monks



With some popes

MacDonalds, Burger King and KFC get into the act.





Spongebob has been there.



The chickens have crossed the road.

You don't know how much I just laughed. Hilarious!!

The Beatles take a stroll across a potato field.

Looks like a sudden repeal of the law of gravity.

Well whaddya know. Monkeys evolved into John Lennon.
