Progressive enhancement is an escalator that becomes stairs.
Graceful degradation is building a lift, then having to add stairs.

I like an escalator because an escalator can never break, it can only become stairs. You would never see an ‘Escalator temporarily out of order’ sign, just an ‘Escalator temporarily stairs. Sorry for the convenience. We apologize for the fact that you can still get up there.’ — Mitch Hedberg
