In the beginning Richard (on the right) asks John(on the left) to go to a picnic. It was a beautiful day for a picnic Richard thought and that's why he asked John.
John and Richard went on the picnic but John had to go to the restroom and while John was gone Richard ate all the lucky charms that they had brought. When John came back he got mad and pushed Richard then Richard punched John and they got into a fight.
As John and Richard were fighting Richard punched John so hard he flew into the side of mount Olympus knocking over Hercules' crib. That got Zeus so mad he put Richard and John in the underworld.
After being pushed into the underworld John and Richard Started fighting in Hades' living room. That woke up Hades and he made Cerberus start chasing them which caused them to get out of the underworld.
After the underworld they came back to the picnic spot and they noticed Richard's grandpa and then Zeus comes down and kills Old man Mel. Then Richard knocks out Zeus and Richard and John get back to fighting, but then Richard punches John so hard he creates a rainbow out of his blood.
Then Zeus wakes up and ends the fight. But Zeus starts yelling at Richard for knocking over Hercules. After their argument John comes back and Zeus casts a spell on the two leprechauns that makes them never stop fighting so we can have a rainbow.
