Mariann from Brooklyn is a frequent caller obsessed with Howard. Due to her gravelly and grating voice, Fred plays sounds of crows cawing when she calls. (She likes to sing the line, "All I need is Howard in my life" to the tune of Enrique Iglesias' The Rhythm Divine).

Mariann is a 47 year-old homemaker who lives with her 22 year-old son Patrick, 13 year-old daughter Nicole and husband (name and age unknown). The first time the Stern crew met her in person, they were shocked to discover that she is relatively attractive. She recently rode the Sybian fully clothed and did not like it.

Mariann called the show on September 11, 2001 to report her sister missing, who, as it turned out, perished in the terrorist attacks.

On May 17, 2006, she called the show and tried to talk to Artie Lange about the dysfunctional situation with his girlfriend Dana Sironi. Artie became defensive, calling Mariann an "unfunny cunt", to which everyone responded in mild disgust, as Mariann seems to have good intentions. She "diagnosed" Artie with "Sad Clown Syndrome". She did not ask for an apology, but instead participated in Lange's roast on the evening of June 8, 2006.
