What is mr kitzel?

Mr. Kitzel is a character from The Jack Benny Program, a popular American radio and television show that aired from the 1930s to the 1960s. Mr. Kitzel was played by actor Artie Auerbach and was a frequent guest on the show, known for his high-pitched voice and infectious laugh. He was often the subject of Jack Benny's jokes and would frequently be asked to perform silly tasks or impressions. Mr. Kitzel's catchphrase was "pardon me for laughing," which he would say after a particularly uproarious laugh. Despite the character's popularity, Auerbach did not receive much recognition for his portrayal of Mr. Kitzel and was only credited for a handful of episodes.
