Alerted that something is afoot by Katz wearing a bathrobe, Ben learns that he had a woman over the night before. At first he is incredulous ("Shut up, Dad. You did not"), but then believes it and is offended. Katz says with her, "I felt witty, I felt sexy"; Ben says, "These are disgusting things." (She's a neuroanatomist, by the way -- "Before she's had her first cup of coffee, she's killed eight cats".) Laura notices Katz is wearing "something that's trying to be cologne," and Katz explains, "It takes some getting used to," which Laura thinks should be the cologne's name. He tells Julie and Stan it's not cologne, but a medicated powder for a rash. Julie thinks it's "cute" that Katz is having a fling. Katz and Ben go to the pet store ("You're not betrayed by the animals," says Ben coolly) and admire the puppies. Ben: "The great thing about pets is they can pee anywhere." Katz: "You mean they're not inhibited the way you and I are. Or the way I am."

• Bill Braudis: Misses his 11 a.m. appointment and can't reschedule for noon because that's when Katz goes to lunch, but Laura says he can just go with him; played Little League in college (nickname: "Mister"); went to San Francisco and had his nipple pierced -- "It's OK, they caught the guy"; put his contacts in backwards and could see his brain, especially the word "farming," which was the answer to a test question years ago that he couldn't remember (the question: "What do farmers do"); has been married three years and is mad that his wife hasn't given the engagement ring back yet; has been trying to get into shape -- "but there are so many."
• Lew Schneider: Assures Laura he's not crazy; has to check the baby "every seven to 10 seconds"; glad we outgrow the impulse to scream at the top of our lungs when we're hungry, or else there would be some major scenes at restaurants; taking the baby to a single guy's house is like when those exotic animals would be brought on talk shows ("So is he fully grown?" "No, he'll get to be up to six feet, 180 pounds"); accidentally dislocated the baby's elbow and then popped it back in place; he now does this at parties; hates HMOs; wonders about the first time someone ever used sarcasm; talks about having an ice cube stuck in his throat and trying to calculate whether it would melt first, or whether he would die first.
