The video clip may be a bit grainy, but the message of a public service announcement about the federal Equal Pay law from 45 years ago feels thoroughly (and maddeningly) au courant.

Last week marked the 49th anniversary of the passage of the Equal Pay Act of 1963.

The vintage PSA, starring Batgirl (Yvonne Craig), Batman (Adam West), and Robin (Burt Ward) from the 1960s television series Batman, finds the "dynamic duo" in a familiar kerfuffle — tied to a chair in a "deserted warehouse on the outskirts of town" with a bomb ticking just out of reach.

BAM! Batgirl bursts through a door just in time to rescue them before the bomb goes off. But ... not so fast, fellas. First, Batgirl, resplendent in her purple body suit and mask,  has a bone to pick with her male colleagues.
