Furrify myself, then paint a door to a furry reality. :3

I'd do the same, but furrify my friend as well if she wanted me to.

Make the world sane enough for the furry reality to show itself. And shift myself between raccoon man and The Cheetah.

Horrible, horrible things. X3

Seconded!

I don't know, probably go mad with power once I got some practice with it.

i'd help those who sought it

i already have a character concept for that :P but its a pen, not a brush :P and if i really did have one then id go traveling the world to preserve the natural beauty before thigns get destroyed :P and give girls large bewbs :P..... and change my appearance to my kojiro persona.... and other things XD.... and cookies

Paint a second paint brush that lets me do the same thing--just so I can say I have two--and then go at painting up my balloonie fursona, followed up by several dreamy pretty girls. Then once I'm bored with that, I'd probably paint myself as the beloved and benevolent dictator of the world (or a peaceful anarchy, since it can only happen by magic). Of course, it'd all look pretty crappy since I can't paint...so I'd probably have to draw up some painting talents with the second brush I made.

Save teh world. Maybe.

Probably after I've had my fill of using it to be a dick. :D

...And that's something that's -really- hard to get sick of.

turn everyone who's abused his/her power into a baloonie and make Jules Verne-style airships out of them.
and maybe create some furries so society can get used to them a little bit. especially those who deem everything out of their own petty little world strange, and thus dangerous and fit to be destroyed at all means.
on second thought I'll turn THOSE into furries first...

After having a little fun with the thing I'd probably wind up destroying it to be honest. Letting it exist would just be too dangerous.

Paint the world a better place. Starting with our damn president >.< And, yeah, make myself look more like my furresona, as well as my friends. Lets not kid ourselves >.< Or at least clean myself up a little bit.

Probably sell it on eBay

1) Paint myself a mate. 2) Make unicorns and dragons real. 3) paint up impeachment papers for Bush

Then I would paint up a nice home for myself, friends and family, and a place where I could have a convention localy as well as a way for me to attend the cons elswhere.

There are too many things I would paint and erase with it to put here.

I'd...take painting lessons. >.=.<

I'd make inflatable furries a reality. Yes I would.

Make the cake not a lie. And make lots of nifty computer things.

Handlebar-face-mustaches for ALL!!!!!

*GIGGLES!!!*

And, after that... a WHOLE lotta fwoomping! I'd paint little pool-toy nozzles all over the place!

Most likely, the world would flop into 2d, and have angry and demented stick figures running around.
