Okay, I got this idea from someone on the Glee Wiki. I'm just changing it a little. So you know the Glee Time Game that's posted on here? Well, it's sort of the same concept. You make a sentence according to your birthdays.

Choose the month you/a friend/someone you know was/were born in:
January- "You swap lives with..."
February- "You suddenly wake up naked beside..."
March- "You sing a duet with..."
April- "You become best friends with..."
May- "You get asked on a date by..."
June- "You get randomly kissed by..."
July- "You get married to..."
August- "You get slushied by..."
September- "You are handcuffed for like with..."
October- "You fall in love with..."
November- "You are haunted by the ghost of..."
December- "You'll have a baby with..."

Now choose the day you were born on:
1- Finn
2- Kurt
3- Brittany
4- Sebastian
5- Will
6- Mercedes
7- Tina
8- Quinn
9- Rachel
10- Puck
11- Mike
12- Rory
13- Sugar
14- Harmony
15- Santana
16- Unique/Wade
17- Sue
18- Blaine
19- Jesse
20- Dave
21- Holly
22- Sunshine
23- Terri
24- Roz
25- Joe
26- Sam
27- Beiste
28- Artie
29- Cooter
30- Emma
31- Matt

Then just create the sentence. Pretty simple.
