The only body part that's furniture, cushion, and punchline simultaneously.

means The two fleshy rounded parts of the body you sit on.

from From Old English 'buttuc,' meaning a short end or rounded strip of land (like the end of a ridge in a field) — the word first described a stubby protrusion of ground before it settled permanently onto human anatomy. 'Butt,' its blunter cousin, comes from related roots meaning 'end' or 'thick end of something.'
