True story I ran into both of them. My best friend worked at Waynetech enterprises and invited me to the annual company picnic when the Mad Hatter put most of the people under mind control. I hid, so I was fine. Bruce Wayne was there and despite being close enough to punch the loser in the face did nothing and ran away as soon as he could. Luckily Batman showed up minutes later and saved everyone.
With Clark Kent I don't get the guy. I was working a hot dog stand in Metropolis and he'd usually pop by to get one and say they reminded him of back home from wherever he's from small city or something. Some nutcase blows up a car a few blocks away and he makes the most retarded excuse that he needs to use the bathroom when he's clearly just scared and runs off. He missed Superman cleaning things up too.
Put those two in a ring and make them fight and they'd probably make up a million excuses like a bad back for why they can't go on
