Why Hobbit's Dudes had to shave off their beards?

Answer:
Because They hadn't 10 years to grow them up.

You probably heard about Gary Weddle, teacher from Washington who had not shave his beard since 2001 - 3454 days?

Gary from 2006 HERE article in Guardian, and article in Reuters from 2011 HERE.

Gosh...how I miss this beard..

:/

Maybe Sir PJ can give a little chance to ZZTop guys? They can do this without special characterization, like was in Back to the Future III.
