Fallon endeared himself to audiences pretty early on in his SNL run. He seemed like some kind of great mix of Adam Sandler and Mike Myers, playing guitar, doing impressions, etc. He quickly wore out his welcome, however, as he reached new levels of annoyingness: laughing incessantly during every sketch in which he appeared, creating obnoxious characters, and finally, leaving SNL to make terrible, terrible movies. And now he's going to replace Conan as host of "Late Night?"
Wait, maybe I'm wrong. Maybe he actually created awesome characters. Remember the college dude who taped himself on a webcam? Or the Boston guy who always yelled "Nomaaaaah!" And maybe his movies were actually really good! Y'know, Taxi, Factory Girl, Anything Else. Gems like those. No, wait. I was right the first time. Those were all terrible.
Thus, while there's a chance Fallon may be decent as host of "Late Night," it's probable that he'll continue his streak of awfulness. So join us in proudly predicting that This Will Be Horrible!
