Bizarro is made possible today by Eternal Honeymoon Lingerie.
Yes, this joke is a bit adolescent, but at least I didn't use a basketball. I do have some restraint. Nor did I use a baseball, which, come to think of it, might have been funnier. A golf ball would have been too small to read legibly, as would a hockey puck, which is not "cup shaped" even when cut in half. If her husband were hooked on watching sumo wrestling, I'd have no idea how to illustrate a sports bra for that.
Still, lots of people like visual puns, that's how Carrot Top got rich, and I like to cater to my entire readership, not just the sophisticated humor connoisseurs who frequent this blog.
