A man tried suing PepsiCo after allegedly finding a mouse in his Mountain Dew! 

 On November 2008, Ronald Ball allegedly purchased a Mountain Dew from a vending machine at work and found a dead mouse in it. He then proceeded to sue PepsiCo for this incident. Apparently, Ball became violently ill when he realized just what he was drinking.

PepsiCo called upon a veterinarian to testify in the lawsuit. The veterinarian testified against Ball when they said that if a mouse had been submerged in Mountain Dew for 30 days, it would have been reduced to a “jelly-like substance.”

After examining the mouse provided by Ball, the veterinarian also decided that the mouse was not even born when the Mountain Dew can was filled and sealed. It was a very young mouse and had been dead when it entered the can. Overall, the veterinarian proclaimed that what Ball was claiming could not be possible.
