The only way you know you’ve truly made it into the pop-culture canon is if you’re featured on Sesame Street.
Following in the footsteps of such kid-inappropriate shows as Mad Men and Boardwalk Empire comes Downton Abbey’s Sesame Street treatment.
This requires no explanation.
“Upside Downton Abbey” is goofy and wonderful and completely upside-down. And, of course, provides some important lessons about gravity.
After all these years Sesame Street is still doing it right -- making sure grown ups aren’t totally annoyed by watching your program.
