Quote from Axl in Adult Swim
Frankie: Oh, before you take the suit off, maybe you should check the pocket... make sure your wallet fits. Axl: Oh, I don't carry a wallet. Frankie: [v.o.] Don't say it. Don't say it. Don't ruin the moment. He's a grown-up. He can do what he wants. Frankie: Really, Axl? Are you kidding me? You don't carry a wallet? That is so dumb! Where are you putting your money? Frankie: [v.o.] I said it. Axl: I put it in my sock. If I'm not wearing socks, I put it in my shoe, and if I'm wearing flip-flops, roll it up, tuck it behind my ear, where my illustrious hair holds it in place.
