Since puzzle jokes are the theme of the week, here's how I first heard this one: a half-dozen blondes walk into a bar and order a pitcher of beer.

The bartender brings out a pitcher.  The blondes pour themselves a round, raise their glasses, shout "TWENTY-SIX DAYS!", clink their glasses together and drain them.

They order another pitcher.  The bartender brings it out.  The blondes pour again, raise their glasses, shout "TWENTY-SIX DAYS!", clink their glasses together and drain them.


They order another pitcher.  The bartender brings it out, and asks, "What is it you ladies are celebrating here?"  One of the blondes replies "We finished a jigsaw puzzle that said 4-6 years, and we did it in JUST TWENTY-SIX DAYS!"
