Slurm

Slurmis a fictional soft drink in the Futurama universe. It is popular and highly addictive, and is Fry's favorite drink. It is widely seen throughout the universe. Slurm delivery trucks can be frequently spotted, including in the Futurama opening credits (shortly before the Planet Express ship crashes into the billboard). The drink's slogan is 'It's Highly Addictive!' and its distribution is handled by Bureau of Soft Drinks, Tobacco, and Firearms, a parody of the Bureau of Alcohol, Tobacco, and Firearms (which is now known as Bureau of Alcohol, Tobacco, Firearms and Explosives).
