Jimmy and Carl volunteer to stay on a rooftop for a radio-thon to raise $25,000 for childhood mutism. Jimmy sees this as an escape from teething Otis and cranky Beth, so he leads Beth to believe that he was required to partake of the event by KHOR. Beth and Pam dine out, and Beth soon sees Pam flirting with a waiter. Since Pam's now dating Carl, Beth sets out to get Pam to stop her flirting ways. Soon, however, Beth shifts her focus to Otis and his first word, "Da Da" (and her jealousy that he uttered Jimmy's name before hers). Her phone call to Jimmy sees him fleeing the rooftop to be with his family... until he slips and admits that he volunteered for the radio-thon. So he flees again from the crankier-than-usual Beth, and tries to make it up to her by going to extreme lengths (hanging upside down from a rope) to get the money raised so he can go home. Touched by his gesture (and scared for his health), Beth goes on the news to plea for money for charity so that Jimmy can leave before he sustains permanent damage.
