New Yorker Cartoon

I don't agree with Jerry Seinfeld that the New Yorker's cartoon's are inscrutable or unfunny, but the small illustrations can be dodgy. Usually they are small and poetic, a pair of glasses on an open book, a whisk, etc. But sometimes they are compact and timely stories.
Here we have two superheroes one with plain socks and a polka-dotted cape, the other, more conservative, with striped socks and a plain cape. He comes either from a University abbreviated as A, is known as A man, or has magnetic capabilities. The first (D) is flying towards him with a ringing cell phone. "Get with the times" he says.
"No, no, I won't" says A.
