oh, yeah, and then there's "my ding-a-ling" by (?) chuck barry:

when i was a little bitty boy
my grandmother bought me a cute little toy
silver bells hanging on a string
she told me it was my ding-a-ling-a-ling!

chorus:
oh, my ding-a-ling
my ding-a-ling
i want to play with my ding-a-ling
(repeat)

once i was swimming 'cross turtle creek
man, them snappers all around my feet
sure was hard swimmin' 'cross that thing
with both hands holdin' my ding-a-ling-a-ling

then mama took me to grammar school
but i stopped off in the vestibule...
every time that bell would ring
catch me playin' with my ding-a-ling-a-ling
