Two heroes stand over a minion that’s sitting on the ground, tied up.
Hero 1 [gesturing to minion]: Don’t worry, he’s telling the truth.
Hero 2: How can you tell?
Hero 1 [smugly]: When someone lies, their heart rate goes up. I can hear it with my super hearing. It’s a natural lie detector.
Hero 2: Wow, that’s really useful.
Hero 2 [blushing]: So, umm, I was wondering… maybe after this, if you might want to go out for dinner…?
Hero 1 points a dramatic finger at Hero 2.
Hero 1: Liar!
