When Randy tries to fit in the fraternities, he bakes cupcakes that have icing on them that spell out "Be My Pal". After his plate is disturbed, he is holding four of them reading "lame." This is only in the US release of the film. All other versions simply have happy faces drawn in icing on each cupcake.
Also on Mike's calender the US version says "Scare Finals", all other versions use the same "happy face" from the cupcakes.
