Mondegreen

This week I've had a running theme on mondegreens going. Don't know what those are? Wikipedia to the rescue:

A mondegreen is the mishearing (usually accidental) of a phrase as a homophone or near-homophone in such a way that it acquires a new meaning.

This can be particularly amusing when it relates to songs:

• "Sweet dreams are made of cheese."
  
  
• "Shot through the heart, and you're too lame."
