Edna was a rather large woman because Jeff was...well...a rather large man. (In a conversation with a radio co-host, Jeff once said that he wasn't going to tell Beckie that he had a weight problem until after they were married.)
A couple of months after their wedding, Jeff, dressed as Edna, was involved in a promotional photo shoot for the radio station. Afterward, still wearing his full Edna outfit and using his Edna voice, he thought it would be fun to pay Beckie a visit at her place of work, the hair salon where they had met.
Beckie was at the back of the salon, shampooing the hair of an elderly client, when she heard the commotion as Edna entered the shop, calling out "Where is Beckie? Where's that Beckie that married Jeff C.?" When he had worked his way back to the sink where she was working, she found herself in the awkward position of introducing her client to her husband, who was dressed as a woman unlike any other.
Well, being the competitive person she is, Beckie determined to get even with her practical joker of a husband. So she conspired with Jeff's boss, Char, to call in during an on-air call-in program; but Beckie would pretend that she didn't realize she was on the air.
