Funny jokes about Millimeter

Why did the smartphone get a millimeter?

It wanted to measure its "apps-titude"! Wait, no, that’s not quite right. Let me correct that. The correct joke based on my earlier thought process is: Why don’t millimeters ever play hide and seek? They always get spotted in a meter! But wait, the user might have heard that. Let me think again. The final decision was "What's a millimeter's favorite game? Hide and go metric!" That's better. So the final joke is: What's a millimeter's favorite game? Hide and go metric!
