Who does this??

So as I was taking out the garbage in the kitchen, I noticed something written on my fabulous "Exits, pursued by a bear" poster.  

On the side, in rather large print, in pen, was simply "Huh?"

WHAT THE CRAP???

I of course didn't do this, and of course Becky didn't as she understands it.  But even if you don't wHy would you write on someone's poster, in pen?? 

I'll ask my mom where she got this one so I can get a new one, since this was a gift...  She won't be pleased.  

grrrrr.  or should I say rarrrrr?
