Dildo Sagwash was a Jedi Knight during the Clone Wars with the bare minimum required Midi-Chlorian count. He had only slightly more than the Jedi Temple Custodian. He was barely able to turn his lightsaber on, let alone wield it. He was also way grumpy.
Dildo was considered a youngling well into his twenties, and became a frequent target of ridicule among the younger students. One night after he passed out on the couch in the youngling dorm, his classmates tatooed the word, "penis," down the side of his head in an ancient Jedi language. They told him it meant, "Awesome Jedi," so he never bothered having it removed.
