Panel 1: We find ourselves watching Elly try to answer the phone only to have her say "Hllllhhhhhh" instead of "Hello." Her sudden inability to speak naturally alarms her.
Panel 2: As someone I'll call Myrtle Gronvlop asks if this is 555-4590, a horrified Elly realizes that she's lost her voice.
Panel 3: Myrtle won't give Elly much of a chance to answer when she badgers her with questions like "Who is this? Who are you? Who am I speaking to?"; since Elly can't talk, all she can do is make incoherent wheezing noises that sound a damned sight like the stereotypical heavy breather on the phone.
Panel 4: Since Lynn's muse is the sort of sitcom that led Cesco Marciuliano's kid brother to ask why everyone on Bewitched was a high-functioning alcoholic, Myrtle alarms Elly when she tells her husband Edgar to come quick because she's got an obscene answer. Elly is, of course, worried that she'll be arrested for sex fiend crimes because Myrtle is a prurient sitcom dough-head.
Summary: I know that I might offend some people but God, I hope that there are no notes because if there are, they'll be "This is the truth!! This happened!! You can't make this stuff up!!" and so on and so forth because this is just stupid enough a situation to have actually happened to someone.
