For nearly two decades now, my dad has held firm in his belief that Will Ferrell and Red Hot Chili Peppers drummer Chad Smith are the same human being and have never been seen together in the same room. It's something he brings up multiple times a year, every year, since Ferrell first joined the cast of Saturday Night Live in the mid-’90s.
My dad's obviously not the only person to note the strong resemblance; Ferrell and Smith agreed to a "drum-off" on The Tonight Show following a fake internet feud that began after Ferrell's Reddit AMA three months ago. Tonight, that drum-off happened.
I told all this to my dad. He reminded me that The Tonight Show is pre-taped and that special effects are pretty advanced these days. So it goes.
