Skeletons Can't Breathe Underwater

I have a theory. I believe that once a group gets above 25 people, there is bound to be at least one person that insists on verbalizing everything he/she is thinking in an attempt to get people to laugh. Relative to this theory is that in a group of 25+ people watching a movie there is always someone that must show off how intellectual he/she is by commenting on the technical aspects or on how realistic things in the movie are. 

A prime example of this happened to me when I was in high school. After a choir concert, my friends and I went over to a girl's house to watch the newly released on DVD and highly anticipated movie Pirates of the Caribbean. Sure enough, in this group that role was filled.

In the movie, the cursed pirates take a walk on the ocean floor in their true skeletal form. The sequence is very climactic and epic. The skeletons walk very slowly and eerily. Sure enough, this girl pipes up, "Yeah right. Like those skeletons could really hold their breath that long."  I didn't know how to respond. Did she hear herself? Where was her mind-to-mouth filter?

Another example happened just a year or so ago. I was at work and we were watching The Brave Little Toaster. A co-worker that was the out-spoken engineering-minded individual in this group reassured us the movie was fake by observing that "It is physically impossible for a toaster to walk and talk."
