10 "Innocent" Songs You Didn't Realise Were Filthy As A Kid

4. Sledgehammer - Peter Gabriel

"You could have a steam train, if you'd just lay down your tracks."

Those weren't tadpoles at the start of this music video, and the sledgehammer in question is definitely not the large metal tool you thought it was. It's Peter Gabriel's penis, basically.

You've got to give it to him - putting out a song so blatantly about sex and have people sing along oblivious to it. It's pretty obvious the suggestion to lay down your tracks (legs) is to let the steam train enter the, ahem, tunnel, is it not? "Open up your fruit cakes, where the fruit is as sweet as can be" - then in comes the sledgehammer!

It's possibly the crudest collection of metaphors possible, in fact it's so bad it's brilliant.
