How will being 19 years old affect me at the Barstool holiday party tonight?

Tonight is the Barstool Holiday party and the folks around the office are absolutely buzzing about. Some people are calling it their favorite day of the year, meanwhile, others are saying that they could take it or leave it. This is the first time I've had a job where there was even a Christmas Party (that I know of), so I have absolutely no idea what to expect.

One of the main things I've heard is that this is one of the biggest days of the year for the people who work on the third floor because it's their time to shine. There are even some people on the content floor, especially a one Glenny Balls, that are pretty excited about tonight's festivities

However, some people* are "too young" to partake in the drinking portion of the evening, the whole point of the holiday party - or so I've heard. Quite frankly, I'm not even sure I can get into the party just because I was born two years too early. Sure, I got the invite. Sure, I responded saying I'll go. But, just like everyone who was ever under the age of 21, I could get asked for an ID and it could be curtains for OMTE's Holiday party excursion. 

*I am the only one under 21 (I think)

There are various possibilities for how tonight will go for me:

-I get in because no one cares that I'm 19 besides the bartender

-I get asked for identification, nervously hand over my expired learners permit, get laughed at, go to Grand Central and go home. Jealously look at pictures of everyone having fun on the internet, meanwhile, I'm on a train home being sad.

-I get denied, then convince someone who is short (cc: kbnoswag) to sit on my shoulders underneath a trench coat and get in that way

rough sketch:

-I get in, become one of the people who don't like holiday parties and just leave anyway

There are literally infinite possibilities of what will happen tonight. Even if I get in, I'll probably be getting chirped for drinking like 4 sprites because I'm not allowed to consume alcohol at my age. I'm just hoping that whatever happens, I don't get embarrassed in front of everyone. Whether it's because I get turned away or because I'm caught crushing a zillion Pepsi cans (s/o Dana B), just hoping for a good night.
