No-Shave November has been a pretty great month around TODAY, with viewers (and staff!) going from smooth to scruffy, all in the name of raising awareness for men's health.

But one of our favorite parts of No-Shave 2015 has been having "The Greatest" participant ever: Namely, championship boxer Muhammad Ali, who's been updating us on Twitter with his progress.

And while this month is coming to an end, Ali told TODAY that he likes his beard so much, he's going to keep growing it!

Here's the champ's most recent photo:
