Me and my friends have a couple:
Sam: Teddy-bear
Elrond: Freaky-eyebrows-dude (I see this one is quite popular!

)
Gimli: Da Beard from da Block (In your best ghetto voice!

)
Legolas: Dumb Blonde (No offence to any of the blondes out there; I myself am a dishwater blonde, (I hate that! Someday I'm gonna make up a new name for dishwater-blondes. It's just not fair!) so please don't take offense!)
Arggghhh!!!!! Alll of a sudden my mind just went blank!

Oh well...I'll be back! (Said in best Arnold S. voice. ( I'm not even going to attempt last name!)
See ya later alligator!!
