When Mark Ruffalo went on The Tonight Show last night to promote his film Spotlight and be adorably bashful, Fallon took this as an opportunity to embarrass the 48-year-old actor. After chatting about how Ruffalo's kids have no interest in seeing him playing a dad or romancing a lady who isn't their mom (cute), Fallon pointed out that with these parameters Ruffalo can show his kids a Clearasil spot he did in 1989. Joke's on Fallon, because Ruffalo and his baby face killed it in this commercial.
