Here's a simple shooter that should please any Tequila drinkers who like to take things up a notch.  The recipe called for Tabasco, but feel free to use your favorite hot sauce.  Sriracha, Texas Pete, or a Wasabi/Horseradish combo, will all do the trick.  If you like a shooter with a little bite to it, definitely give this one a try... Chainsaw.  Cheers!
1.5 oz. Tequila
.25 oz. Rose's Lime Juice
.25 oz. Lemon/Lime Soda
5 - 10 dashes of your favorite hot sauce
Cracked Black Pepper to garnish
Put a little Black Pepper on the rim of a Shot glass.  Put all of the ingredients in an ice filled cocktail shaker.  Cover, shake well, and strain into your shot glass.  Bottoms up!
