Admittedly hard to believe but Ive heard that claim. There are also people claiming to watch something called golf and paint drying championships.
Paint drying championships I could understand watching at least to the commercial break before changing the channel, but golf and baseball is an instant channel flip.
Oh, the BEST Sunday afternoon slowdown by far is Al Blade lawnmowing channel on YouTube. He finds really bad, weedy, junky yards and cleans them up for free. Just 1+ hours of pure lawnmower engine humming in the background. Makes for a great nap.
Personally, I draw the line at competitive lawn mowing. Those little John Deere tractors have just ruined it.
