Some of the best parts of movies like Old School and Zombieland are their unexpected celebrity cameos. The same thing happens in comics, every once in a while. Here's a look at another Celebrity Cameo!

Marvel's Double Dragon limited series was based on the super-cool video game franchise and stars the brothers Jimmy and Billy Lee, experienced martial artists. This comic series introduced their father, Stan. You heard me right. Stan ... Lee. So, interestingly enough, the father of the Double Dragon brothers is Stan Lee ... and get this, he knows KUNG FU, too! Not sure if this is part of the video game canon - but it's a fun bit of trivia.
