Coral snakes - their related to the cobra, quite numerous in Texas, and are extremely poisonous. Valentin Grimaldo - he is a Texan....need we say more.
It was not a prank, apparently a snake crawled into the money dispensing slot of an automated cash machine in Mexico.
However, when it tried to crawl back out it got stuck, much to the astonishment I'm sure of the next ATM customer.
