Debbie Grund was an employee of Strickland Propane and one of Buck Strickland's many mistresses. She was a silent character, never having an on-screen speaking role until the episode "Hanky Panky," when she was voiced by actress Reese Witherspoon.
After discovering her husband's affair, Miz Liz kicked Buck out and took over managerial duties at Strickland Propane. She placed Debbie on tank wipe, which according to Hank is the worst paying and most degrading position.
Debbie was a central character in Hanky Panky. After Miz Liz takes over Strickland, she demotes Debbie to tank wipe. Feeling rejected, she pursued Hank’s affections — only to be rejected by him as well. She finally snapped when the Stricklands made up, and intended to shoot Buck and Liz (and maybe Hank and Peggy) with a shotgun. As she juggled the gun and a snack as she tried to hide out in a dumpster, she accidentally set the gun off, resulting in an accidental suicide.
