Colorado Birthday

(This concept was originated in Colorado and debuted in Chicago)

As you are performing coitus in the doggie position on your lover's birthday (or anytime really) - Step 1. Light a candle and stick it into a cupcake -- Have at ready! Step 2. Slowly and gently bring the cupcake forward towards your partner's view. Step 3. Sweetly whisper 'Happy birthday' in your partner's ear. Step 4. (now this is the tricky part and takes precision timing) As you conclude your birthday whisper, swiftly remove your penis from your partner's vagina and abruptly insert it into the anus and provide one muscular thrust inward (trap ALL that air!). CRITICAL STEP!! - Once she rears back in shock from the surprise birthday entry, strategically position the cupcake WITH lit candle directly in-line of the beehole while simultaneously plungering your schwantz out with great torque, friction, and quickness for the best airy effect (chef's kiss). If done correctly and the timing is just right, this will extinguish the candle's flame all in one assertive, swiveling exit.

Now to Step 5 - At this point, your birthday girl may have thought the surprise was over -- but oh no. Step 5. After the candle has been properly extinguished, bring the cupcake back to your lover's view to make a wish! Step 6. As the wish is being verbally shared, begin to sensually smear the cupcake all over her face while singing 'Happy birthday to you....happy birthday to youuuuu...' ---- She'll never forget it! :)

Birthday paradox

In probability theory, Birthday paradox is the phenomenon concerning the probability that, in a set of n randomly chosen people, at least two will share the same birthday. The birthday paradox is the counterintuitive fact that only 23 people are needed for that probability to exceed 50%. The birthday paradox is a veridical paradox, i.e. a paradox that produces counter-intuitive results, but is demonstrated to be true nonetheless.
I always thought it was super rare for two people to share a birthday, but the birthday paradox says it only takes 23 people to make it likely!
