Wearing a skull loses it's name

1. make a world (an old one will do, too)
2. /give <Username> skull 1 3 {SkullOwner:MHF_Blaze}
3. It will say "MHF_Blaze's Head"
4. Put the skull on your head.
5. Take off the skull.
6. It will just say "Head"

The quotes were added, that's not what it shows 🙂 .
If you put it back on it looks like a blaze. 😛

Note: It doesn't have to be MHF_Blaze, It can be just about any (custom) skull.
