15. THE POT-SMOKING DOG IN ROAD TRIP (2000)

Anyone who’s ever puffed the magic dragon knows that a person’s first hit of weed is always followed by a hacking cough. Handling the potent herb takes a little bit of practice, unless you’re the dog in Road Trip. The pet’s owner blows a large smoke cloud into its face, yet the four-legged champ hardly winces. Like a true G, it wastes no time demanding snacks and grilling the blunt-holder with glassy eyes and a squinty brow. Snoop Dogg would be proud.
