This video shows my completed TV-B-Gone coffee cup.
Take one clean, empty coffee cup and, using an X-acto knife, cut a little window for the four infrared LEDs in the side near the bottom of the cup. Position your TV-B-Gone in the bottom. Cut a little hole out so you can access the switch from the bottom of your cup. Drink coffee (ahem) and savor the bewilderment around you. Here's the link to the Instructable: tinyurl.com/5eamqa
