Superficial cervical plexus block.  

Most find this an EZ block.  Very satisfying for:
1. Clavicle fractures
2. I&D of those abscess patients get under the chin in the shaving area.  
3. Lacerations of the ear lobe  are blocked as well.  
4. IJ central lines.  Good practice and if they are awake, really makes it a completely painless procedure.
