Steve gets hit with snot bombs on three occasions. Unfortunately for Steve, this was the hardest part to catch on film. The crew made four devices and tried several methods to get it to work. Each time you see him sneezed on, it's using a different method though the last shot which was the first sneeze was everyone's favorite. The device used was dubbed the 'snot gun' and it was used again for the explosion in Hildegard's scene.
