The bug crawled into his foot...
...and then came out through the neck?! Ewww....... Oh, who am I kidding? That whole damn sequence was cool. I even enjoyed the part where the clown ate the bug and then spat it out through his stomach. The only thing that bothered me is that the clown's face seemed to lack emotion, but I guess it makes sense that a person with a shriveled up skeleton face would show very few facial expressions.
