This has to be the most blatently obscene song I have heard for a long time (mind you it really belts along and I turn up the radio whenever it’s on) so how the hell does it get commercial airplay.
For instance:
"Vulcanize the whoopee stick
In the ham wallet
Cattle prod the oyster ditch
With the lap rocket
Batter dip the cranny ax
In the gut locker
Retrofit the pudding hatch
Ooh la la
With the boink swatter"
or maybe
"Marinate the nether rod
In the squish mitten
Power drill the yippee bog
With the dude piston
Pressure wash the quiver bone
In the bitch wrinkle
Cannonball the fiddle cove
Ooh la la
With the pork steeple"
It doesn’t seem that obscene to me–it’s just talking about sex. Judging by the lyric snippet’s you’ve posted, I think it’s rather funny. Now, if it was talking about rape or crimes of violence, that would be obscene…
So to answer your question, it gets airplay because it’s obscene, and apparently (at least in your opinion – I haven’t heard it) it’s catchy. That’s how.
