The Hilarious Nickname Mike Tindall Created For Prince William

In contrast to William, Prince of Wales' single drink, Mike Tindall has been known to imbibe more alcohol in his former rugby career. "It is built on the social aspect and a couple of beers being sunk quite often," Tindall explained on the podcast "Seven: Rob Burrow." Back in 2003, Mike was said to have attempted to break a sports drinking record. After his rugby team won the World Cup, Tindall allegedly drank almost 50 beers during the flight from Australia to the U.K. However, he didn't succeed at surpassing cricket player David Boon's record of 52 cans while in the air.

After revealing William's "One Pint Willy" nickname, Mike apologized to the prince, and Zara Tindall jokingly scolded her husband. Mike and William continue to enjoy a close connection. The two cousins-in-law look happy to see each other at royal events and even hugged at a polo match.  In addition, both are dads to three children, and their kids also share a tight bond. 

Mike isn't the first person to point out that William has less of a tolerance for alcoholic beverages. Back in 2010, royal author Katie Nicholl observed William and Catherine, Princess of Wales as they partied at clubs. Kate, who's a fierce beer pong competitor, was able to drink more than her future husband. After multiple shots, "she's the one (left) standing and William is the one who's looking totally out of it," Nicholl reported to CBS News.
