pixar high security SCIF sequence

[s_gru]

i remember there was a clip from youtube or somewhere that showed what i think i remember as a pixar film clip of a man entering a high security scif. he had to scan his eyes, fingers, but then at the end the last scan was him doing a butt scan. does anyone know what movie that was from or where i could find it on the interwebs?

thanks,

FOUND IT! it's a clip from monsters vs. aliens.
