David's romantic plans for Karen's birthday go awry, while Sam and Judy's marriage counselors give them a new "empathy" drug to tap into their romantic feelings, and Misty sets Wheeler up on the world's worst blind date.

David is hired to film a sex tape for middle-aged swingers from the club, but the experience isn't quite the stuff of fantasy. Meanwhile, Karen tries her hand at modeling for Barry, and Judy throws a party for the students in her real estate class, to Sam's chagrin.
