In tribute to today’s birthday girl, here’s a very young Christina Applegate appearing in a Barbie commercial from the 1980s. You know, those really annoying old commercials where girls would talk to their Barbie dolls and gush about pretty they looked! Did I mention these commercials used to bug the crap out of me as a kid? Poor Christina Applegate doesn’t even get any lines in the commercial as she just sits in the background while the other girl does all the gushing!
