Curb Your Enthusiasm Season 3 Episode 2 : The Benadryl Brownie
Nearly five years after the rest of the world, Larry discovers cell phones. Using his new toy, he calls Cheryl and asks her to tell Randy, the chef at Larry's new restaurant, to omit peanuts from the dinner that night because Richard Lewis's girlfriend Deborah is allergic to them. But bad phone reception prevents Cheryl from hearing the message, and Deborah gets sick. A practicing Christian Scientist, Deborah refuses to take medicine to clear up the hives on her face. Richard will not be seen with her at the Emmy Awards that night, so he and Larry concoct a plan to bake a batch of Benadryl-laced brownies for Deborah to eat. The ruse fails, and that night on national TV, the Davids see Joan Rivers lambasting Richard and his none-too-attractive date on the red carpet.
