Get the sup m8mug. Seriously one of the best things I've ever heard from a movie. What movie? THE DOG MOVIE OF COURSE. The Dog movie is honestly one of the best movies ever, it even tops the hit film, Morbius. I have memorised the whole frickin script for the Dog movie and let me tell you, there a lot of banging quotes there. Please do yourself a favour and go watch the frickin Dog movie.
