I just watched last night's House on my TiVo. At the end of the program, where it asks you if you want to keep or delete, a gray box with a yellow star shows up below, "Free Touch of Gray by Just for Men(TM)". If you see this at the end of a recording, all you have to do is select the box, and then follow the "Free Box" choice, to "Yes, send me a coupon for a free box". It says the coupon should arrive in 2-4 weeks, and that the coupon is valid until June 30, 2009.

I see that the offer also appears in Showcases, so it appears that you don't have to use a House episode to get the free coupon.

tis legit, I see it too. They had an offer last month for a coupon for free Coffeemate to be sent. You need to make sure that the TiVo that you use is connected to a phone line though, FYI. Good post
