It's a wide wide world. Fortuitously, you can now do shots wherever you roam. Clip the uncommonly handy collapsible keychain shot glass onto your key ring, belt loop, or handle of your liquor jug and head out on your adventure. Oh, you're getting thirsty? Uncap, pull apart, pour and shoot, then slap it shut and re-cap. Off you go again, with a little more pep in your step this time.
