St. Patty's Day Grenade

When you throw a McDonald's Shamrock Shake into a large crowd of people on St. Patty's day, resulting in a large crowd looking like it has been covered in a green semen. What might happen if a leprechaun skeets on 5th avenue in Manhattan.

1:"Watch this."
(throws shamrock shake into crowd)
2:"Oh my God. It looks like a leprechaun skeeted on them"
1:"That would be a St. Patty's Day Grenade."
