Sarah was putting some hooks up on the wall.

Sarah: [grunting with effort] This is kind of tough. You're lucky I'm so strong.
Me: You are strong.
Sarah: You're just saying that because I'm doing work.
Me: No. You've been working out. You might be stronger than me.
Sarah: Should we arm-wrestle?
Me: Okay.

Sarah put down the screwdriver and we arm-wrestled. It was close, but I won.

Me: Well, I just beat you.
Sarah: You're stronger. So YOU should screw the rest of the hooks into the wall! Ah-ha!
Me: [picking up screwdriver] Oh man.
Sarah: I win!
Me: I knew I should have thrown that arm-wrestling match.
