I discovered a downside to Texas Toothpicks.  They don't stick to my boys beards like the Wishbones, but they leave a very yummy scent in their beards that inspired Maximo to chew off a chunk of his mustache.   
 
 
I'm going to have to trim a little hair on the other side of his mouth so that he doesn't look lopsided.  Hopefully his mustache will grow back quickly.
