Nationals fan vowed in 2012 not to shave his beard until the team wins the World Series

One Washington Nationals fan made a promise way back in 2012 not to shave his beard until the team wins the World Series — and it has been growing and growing ever since.

BJ Treuting — also known as "Bam Bam" — spoke with FOX 5's Bob Barnard early Wednesday morning after the Nats swept the Cardinals in the National League Championship Series.

BJ says if all goes as he hopes, his grizzly looking seven-year-old beard will be coming off soon.

He even promised Bob that if and when he does shave it, he'll do it live with us right here on FOX 5!

You can watch the World Series on FOX beginning on Tuesday, Oct. 22.
