I Got The Words Wrong

Some time's I have lol I think it's funnier of some of the word's my friend got confused with tho. Like west life song fool again in stead of where they sing it's about the pain and the Tear's my friend sang it's about the pain and the teeth.and on grease 2 the reproduction song where Lewis holds up rabbit and says see what happens when a boy and girl don't know how to play it safe but my friend sang see what happens when a boy and girl don't know how to play a tape.and the A1 song take on me where it says it's better to be safe than sorry in song she sang it's better to be safe than subway.lol how she said these quite funny .
