Sproke

Dr. Sprokeberg presenting Sprite and Coke

Sproke is a delicious soft drink made simply by mixing together Sprite and Coca-Cola, and it is enjoyed by many soyjaks around the world. It is unknown when it was first invented, but it was popularized by Dr. Sprokeberg as a treat to calm down patients suffering from schizophrenic delusions. There have been reports that Sproke could worsen hallucinations in schizophrenics due to an unexplained chemical reaction between the two drinks, but these are not backed by peer-reviewed studies, and are likely pseudoscience.

This image is probably a hoax.
