There's a big problem with how we treat old people. We treat them like they're invisible, or non-human. It's kind of like that old couple showing off their butts. You don't expect older people to do that because we don't think they're like normal people anymore. I don't think I'm talking out of turn here. When's the last time you approached an old person and treated them the way you would one of your younger friends? My point is that you don't expect an old person to retaliate on your prank. Well, they totally will.
If anything, I think the old man's picture is better. He has a better expression and there's a sense of irony in the picture. We're used to seeing old people knocked out asleep getting made fun of. It's nice to see the tables turned.
