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

5. Two Become One - The Spice Girls

"Be a little bit wiser, baby, put it on, put it on'Cause tonight is the night when 2 become 1."

Yup, definitely about the old in-out, in-out; but least the Spice Girls practiced safe sex, judging from the lyrics in this song. It's pretty obvious what the Spice Girls meant whenever they sang about "making love to ya" - we just completely overlooked it as young whippersnappers.

Even after reading and re-reading the lyrics out of Smash Hits magazine, we still definitely didn't understand the reference to wearing condoms.
