His long association with brewer Anheuser-Busch earned him the nickname "Mr. Budweiser" and he used that relationship to bring them aboard as one of the largest corporate donors to the Muscular Dystrophy Association. Since 1973, McMahon served as co-host of the long-running live annual Labor Day weekend event of the "Jerry Lewis MDA Telethon". His 41st and final appearance on that show was in 2008, making him second only to Jerry Lewis himself in number. McMahon and Dick Clark hosted the television series (and later special broadcasts of) "TV's Bloopers and Practical Jokes" on NBC from 1982 to 1993.
