If you were able to catch the Oct. 12 episode of Saturday Night Live, then you were probably cracking up over David Harbour's insanely funny Joker spoof featuring the origin story of Sesame Street's Oscar the Grouch. And while I admit I rewatched the clip multiple times, the actor doesn't have anything on Sprout, an adorable Brussels Griffon pup who's putting a sweet spin on the green little muppet this Halloween. After getting the dog in costume, his owner captured the perfect shot of Sprout and shared it to Instagram with the caption, "Who else is feeling a little grouchy today?" And honestly, how incredible is the "Scram!" sign? Talk about a nice touch!
