Bugs with my friend and I's skin

My skin is all buggy and so is my friend's. We are just dinosaurs with 3D glasses on our heads. I checked other people's skins and they're fine. It is only me and him. I will show what I mean (It is just my skin in the picture right now, if you want a picture of my friend's skin I will send it in) This is also Minecraft 1.6.4 (I do not know the codes like 14w19a)
