According to Urban Dictionary:
1. Fez Monkey
The highest level of being, the highest point of evolution. Only a select few ever make it to this.
The Fez Monkey is infinitely more advanced than the normal homo sapien.

Where did you get your fez monkey from?!!!!????
I got it at Archie McPhee’s in Seattle. I’m sure it’s available elsewhere.
