Mister Rogers' Neighborhood/YMMV

Contained examples of:

 * Ear Worm: Just try to get the theme song out of your head after reading this page...
 * The ending theme is even catchier "It's such a good feeling to know you're alive, such a happy feeling you're growing inside..."
 * Fridge Brilliance: Many episodes open with a shot of a flashing yellow traffic light that was in Mr Rogers' house before panning over to the door where he entered. A yellow light (generally) means "slow down" which is exactly what he did with the pacing of his show, especially compared to others at the time.
 * Incorruptible Pure Pureness
 * Memetic Outfit:
 * The cardigans. His mother made them all.
 * One of them is now on display in the Smithsonian.
 * His constant changing of shoes.
 * Nightmare Fuel: Propel, propel, propel your craft, gently down liquid solution, ecstatically, ecstatically, ecstatically, ecstatically, existence is but an illusion.

Didn't contain, but was still related to examples of:
"The fight raged on for a century
 * Dude Not Funny / Sacred Cow / Unacceptable Targets: The Internet is a very raunchy place, but try to make fun of this man and the Hive Mind will eat you alive.
 * Fred Rogers liked Eddie Murphy's parody of his own show, "Mr. Robinson's Neighborhood." To be fair, it was an Affectionate Parody, not deliberate and malicious mockery. Apparently, Eddie Murphy caught up with Mr. Rogers and told him, "You understand, we only do it because we love you."
 * On the other hand, in the late eighties when Burger King made an ad with a fake Mister Rogers explaining why BK burgers were better than McDonald's burgers, Fred Rogers said "You will stop that immediately!"... and they did. This was mainly because he looked too much like the real him, and did not want kids to get confused. By comparison, obviously no kid is going to confuse Murphy for Rogers, and Murphy's sketch was broadcast safely out of the way of any typical child's viewing time.
 * An infamous opening gag in Family Guy featured Stewie terrorizing the Town of Happy and trying to kill Mister Rogers; even series creator Seth Macfarlane thought it wasn't funny. Even so, Stewie's rampage turns out to be a Dream Within a Dream, and it's Mister Rogers who gets the last laugh.
 * Don't even think about repeating the Urban Legend that the name "Mr. McFeely" is a coded innuendo. There's a special level of Dude Not Funny for sick jokes about Mr. Rogers' mother's maiden name.
 * Everyone Is Satan in Hell: Even mainstream news cites him as corrupting youth into things like not being corporate yes-men when they graduate from college.
 * That article takes on a whole new level Hilarious in Hindsight, given the whole late 2000's recession.
 * Fox & Friends also jumped on the same bandwagon.
 * The Westboro Baptist Church did the same thing (obviously).
 * Memetic Badass: Go to the Pantheon and choose Main House. Then scroll down to his entry. Or better yet, go to the DnD wiki -- he's a minor god.
 * It's not just badassery, either. Mr. Rogers can talk anyone into a reasonable exploration of their feelings. According to at least one thread on a certain imageboard, even the Chaos Gods, the Imperial of Man, the Necrons, the Tau, the Orks...
 * And lets not forget The Ultimate Showdown of Ultimate Destiny:

Many lives were claimed, but eventually

The champion stood, the rest saw their better:

Mr. Rogers in a blood-stained sweater"


 * He can out-rap Mr. T. He won't even see it coming.
 * The sweaters are obviously just to hide the tattoos he got as a sniper in Vietnam, after all.
