Dr. Katherine McMichaels: Don't you understand? This is the greatest discovery since van Leeuwenhoek first looked through a microscope and saw an amoeba!
Buford 'Bubba' Brownlee: Yeah, but he wasn't down there *with* the amoebas!

Buford 'Bubba' Brownlee: All this talking about eating is making me hungry.
Crawford Tillinghast: That... will be quite enough of that.
