Keep it together, Uncle Tortoise! (2.5" x 2.5")
Today, on my morning walk, I saw a man who looked exactly like a tortoise. Well, a lot like one. A bit like one. He had a long, wrinkly neck, and deeply-recessed eyes. He looked kind of freaked out, so my brain piped up "Keep it together, Uncle Tortoise!"
Fortunately, my brain/mouth filter was engaged, and I only said "Good morning."
