Bumble Bees and Their Flying Mops

Sera: (pointing to a mop in the kitchen) Does that fly?
Me: What? Does the mop fly? Who do you think would fly with the mop? (I figured she was confusing the mop with a broom, and that we were about to have a reminiscence of witches at Halloween)
Sera: Bumble bees.
Me: Bumble bees fly with mops?
Sera: Yep. Bumble bees fly with mops because they have big mouths.
(WTF!?)
