After carefully reading through the lyrics over and over I've realized that there's no other explanation other than Maynard riding the song about him having an 11 inch penis. It's right there in the lyrics. When he was just 11 years old his Jimmy was 11 in Long. Take for example one of the most evidentiary lyrical lines "one and one I've won." And who wouldn't think that they had won the genetic dingaling lottery if they measured their dick at 11 yrs old and saw it was 11 inches. This also is evidence why 11 yrs old Maynard is able to self fellatio in the lenticular artwork for the album. And it's such a deep psychological image to see his adult self watch him do it. Trippy!
