The story:

Well, it actually wasn't me who misheard them, it was my boyfriend. We were driving down the road and the song came on and here I was singing "Bailamos, let the rhythm take you over Bailamos, te quiero amor mio Bailamos wanna live this night forever
Bailamos te quiero amor mio te quiero" and I stopped to listen to what he was saying and I asked "what the heck are you singing?" and he happily yelled out "buy them boats, let the river take you over buy them boats" I nearly died laughing... my sister can't hear that song without singing "Buy them boats" now .. lol :)
