I was walking back to the car on Sunday after doing the groceries, and saw a white pigeon with dirty brown spots on it's bottom half running across the road.
"Huh" I thought to myself, "where did his arms go?".
"Wait, what?" was my next thought, "pigeons don't have arms, stupid!"
"Oh yeah... but they look so funny without them." I had the mental image of his little arms pumping back and forth in contrast to his little legs.
"Um no they don't. They're birds."
And then I snapped out of it.
I have NO idea what caused that little mental episode but I did have an upset stomach about an hour later - that's gotta be related, right?
