This is a funny 80s song from Spain called "Me duele la cara de ser tan guapo" by Los Inhumanos. You can use it during the health and body parts units or just as a fun filler for the last 3-5 minutes of class.
It's really fast paced and catchy. Definitely cheesy. One of those things where half the class will like it but the other half might be too cool for it. Nevertheless, you'll have 2-3 of them singing it on the way out the door. :D
