Giraffes on a plate
"Hey Jenny, ya ever wonder why there aren't any trees in front of me?"
"Oh George, must you bring that up again? I've told I don't mind handing you leaves from the tree behind you. After all, if you starved to death, I'd miss you terribly."
"I know, Jenny, and I do appreciate that you always feed me too but I just think that, you know, it'd be nice if I could return the favour now and then. If only there was some way I could make myself face the other direction..."
"That's crazy talk, George, and you know it!"
"Why must you always be so dismissive of my ideas, Jenny?"
"Well, for starters, you'd have to stick your head sideways out of the plate to turn around and that simply isn't possible."
What makes you think there isn't a 3rd dimension, Jenny?
"Hush, George! What if somebody heard you talking like that?"
