Every time a fly screams, an ant gets its wings

I'm not sure how I forgot to post this, but luckily I remembered about it today...

Recently my 5 yr old and I were walking down the street and he saw some flying ants, which resulted in me being told the following "fact."

5 yr old: I know where ants get their wings from

me: Where?

5 yr old: When ants want to get some wings, they kill a fly, cut off their wings, and then tie the wings onto their own backs, then move their bodies to make the wings flap.
