Just look at the pride in old Mack's eyes. He loves him some industrial-strength staple-gun boots. He also loves waxing about his career as a top-secret document stapler, deep in the bowels of the CIA. He knows the word 'bowels' makes the younger generation of robots uncomfortable, (also, his referring to them as "Slak-N-Deckers"), but he regales them anyway with tales of covert cold-war document fastening malfeasance from his perch in the unventilated, malodorous Haig bunker (Langley sub-basement twelve).
