You look over the extensive list of drinks, but nothing looks familiar to you at all. Worse yet, there aren't any explainations. You try and ask the bartender, but before he can speak he's called away.
Frustrated, you pick one almost at random. "Brown Cow," you murmer. "That sounds like something sweet."
When he gets back, you ask the bartender for a Brown Cow. He laughs, but reaches below the counter to grab a bottle, "It's a bit of a girly drink, but to each his own."
You scowl at him as he hands you a beer bottle with a large cow on the label. You sniff at it and are surprised that it does, in fact, smell a bit on the sweet side. Tenetivly, you sip at it, then start to gulp. It's not long before you finish the bottle.
"Another?" asks the bartender even as he slides one to you.
You don't hesitate before drinking the second one down. By the time you're done, you're already feeling strange. "I don't feel so good," you say to the bartender.
He nods, "Happens all the time when you're not used to the drinks. Come out here," he says as he leads you out a side door and sits you on a bench. "Get some air, you'll feel better pretty soon."
Once the bartender leaves, you start to realize that your clothes are feeling really tight, to the point where the button breaks on your pants. You struggle to figure out why, but your brain just isn't working right. The beer must have been really strong.
The bartender reappears with another drunken kid, "Wait out here for a bit," he tells him, "You'll feel better in no time." Before you can open your mouth, the man is gone again.
You look at the other kid and realize that he doesn't look right. His head is between his legs like he's about to throw up, but his ears aren't normal, they're pointed. Like a cows ears. Even as you watch, his shoulders get very broad to the point that his shirt tears open at the neck.
You're caught off guard when you feel your hips suddenly buckle and you're forced to all fours. You shake your head and realize that while you watched the other kid change, you were transforming also! You look at your hands only to find hooves. You look back over your body and realize that you have a brown pelt and, even more to your shock, an udder!
Your fall seems to bring the other kid out of his trance and he looks up at you. He stands and you realize that he is still a he, and very much so!
