My friend who played it also combined it with some other verses from a dittie that went

There may be cooties on some of you beauties but there ain't no cooties on me.
There may be fleas on some of your knees but there ain't no fleas on me.
There may be bugs on some of you mugs but there ain't no bugs on me.
There may be skeeters on some of your peters but there ain't no skeeters on me.
There may be flies on some of you guys but there ain't no flies on me.
There may be slugs on some of your jugs but there ain't no slugs on me.
etc....

Easily transferable to whatever tune you'd wish. Have at it and enjoy the fun.
