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 ...
