Wacky Friday

Here is an exchange Julie and Joe had on the way to school this morning:

Joe: "Hey!"

Julie: "What?"

Joe: "Did you see that airplane flying backward?!"

Julie: "No, I missed it!"

[beat]

Joe: "It must be wacky Friday!"

Oh my God, Fans. There is a plane that flies backward in Wacky Wednesday. Our Hero was totally making A JOKE!
