EEEEYE CAAAARRRRAAAAAAMMMMMMBAAAAAA !!!
Take or Import pictures of your friends and see if any has enough caramba to be bestowed a classic sombrero hat and given a proper mexican moustache.
This PunBros Games app is entirely automated: All you do is choose the image you want to run through the EYE CARAMBA program and if anyone gets a Sombrero & Moustache you even have the choice to save it out: unlike many other comedy photo-editing apps, we do NOT require the user to place markers or define areas for the program to work from.
You can even shake the phone to mix the hats up!
