I can tolerate children's programming to an extent, but the one character that truly makes me cringe is Barney. I have memories of babysitting for kids who adored the show some 15 years ago, and that purple dinosaur's voice is just like nails on a chalkboard to me (sorry, PBS!).
Likelihood That It'll Last (on a Scale of 1-10): 8 — My son's already 2. Barney's kind of fallen out of fashion. Unless a preschool pal introduces him, we should be safe.
