In the movie where all of the dinosaurs are on the lose and that fat guy that has to catch that ship crashes his car. Well after he ties the wire around the tree and has his short little conversation with the Dilophosaurus when he slips back up the hill and is laying on his back face to face with the Dilophosaurus and it spits it's black poison at the fat guy it only spits a little bit which splatters onto his jacket and his chin and a little bit on his shirt, well what he really does is grab a hand full of mud or what ever it is and wipes it on his shirt making it look like it was spit on there.
