A few nice funny cartoons images I found:
Adam says, "So, madness means cool?"
"Yeah" replies Malcolm.
Adam says "That’s crazy."
"Malcolm asks, "What other words can you use to mean cool?"
Adam says "Stinky diapers".
Malcolm adds "Monkey butt."
"Clanging".
"Greasy".
"Rusty muffin".
"Diggle"
"Beat box".
"Knobbin".
"Squishy".
"Banana peel".
Into the Brooklyn night my boys searched for the perfect substitute for cool.
