Brooke Mueller Stick Fighting With Twin Sons

Somewhere Denise Richards is saying "I told you so" ... 'cause Brooke Mueller was seen teaching twins Bob and Max how to attack someone with a huge stick Friday afternoon.

Charlie Sheen's ex-wife Brooke took her kids for a walk in Beverly Hills yesterday and began to entertain them mid-hike by turning her walking stick into a sword ... and flailing it around like He-Man.

As we previously reported, her brother Scott was awarded temporary guardianship over the twins while Brooke deals with her latest drug issues ... and he was there too.

It may seem innocent -- but teaching her kids how to wield a giant stick properly when they're being accused of constant violence by ex-guardian Denise Richards seems kinda dumb ... so we gotta ask ...
