How Did You Know? - {day 4}

David K. Israel

Play for your chance to WIN a $100 shopping spree in our store!

Okay, so last month was a bust. We can't apologize enough. But we've fixed the technical difficulties and are really hoping you'll trust us that this month's puzzle will be not only fun, challenging, and rewarding (yes, we're offering the same big prizes we tried to give away last month!) but glitch-free!

For those who missed last month, the five-day trivia hunt has been redesigned and retooled. Thanks to all who wrote in and said the new format is working; I think you'll find even more changes and tweaks this time around. As comments have been turned off for the length of the 5-day hunt, be sure to let us know via e-mail what you think of the retool. You can also hit us up with questions if you find something in the instructions unclear.

As always, it pays to play whether you're the first in with all the correct answers or not. In addition to the $100 shopping spree first-prize, we're also giving away a $50 shopping spree in our store to one random winner who has all the right answers but isn't the first to e-mail them in. Random winners sometimes submit all the correct answers/logic a full 48 hours after the closing bell, so don't worry if you're late or can't submit your final answers at 8 pm ET next Monday.

Have fun with it, and, as always, don't hesitate to work in teams and e-mail all your friends for help. Many, if not most of our past HDYK winners have been teams, not individuals. Because of the screw up last month, we don't really have a reigning champ, which means the floor is wide open. Who'll claim the title?

If you're new to the 5-day trivia hunt, be sure to see the rules and regulations page here. If you missed Day 1, that can be found this-a-way; Day 2 is right over here; Day 3 is down yonder. Now on to our fourth challenge!

Today we're playing Name That Sitcom. On the following page you'll find five short clips from some pretty well-known sitcoms. Thing is, some of them are very old shows. To make things more difficult, the quality of these recordings isn't great. So you're going to have to look for clues in the clips: who are the actors, when were they popular, where is it set? etc. Ready to play? Click on through to the challenge.

And don't forget to tune in on Monday for the final puzzle at 8pm ET. If, for some reason, we encounter another tech problem with the site, the alternate site URL for the final puzzle will be:, so make a note of it!
