That's what I do. Just take a shot of Jager and chase it with Red Bull. It's the same thing, really.

Funny side note: I have about 40-50 alcohol bottles that me and everyone at my house has consumed on top of my fridge. Well, one night me and my drunken friend got the bright idea to pour the remains of the alcohol into 2 shot glasses. We managed to get JUST enough for 2 shots. There were TONS of different alcohol in there, I'm talking: Jager, all diff. kinds of Vodka, Captain Morgan, SoCo, Parrot Bay, Tequila, Whiskey, Rum, anything you can think of.

To top it all off, I didn't have anything for a chaser so we used two slices of bread. Holy CRAP that 1 shot hit me like a ton of bricks. I was fucked. lol.
