Sorry, I'm not shootin' my baby.
She's not in the commercials, but she likes to shop there. She's 12, so we have more important things to fight about.
Alternate suggestion: Get one of those "Classical Samplers" CDs, that have 30-60 second snippets of well-known classical music. Mute the TV and cue the CD randomly when the Old Navy commercials come on. "Danse Macabre" (Alfred Hitchcock Presents), "Hall of the Mountain King" (also dandy for slo-mo sacking of quarterbacks), "William Tell Overture" (Hi-Oh SILLLver!), the last few bars of "1812 Overture"... Many opportunities for humor.
