You can thank Ellen DeGenerers for making the selfie a big "thing."

Now it's time to incorporate it into the Shamrock Shuffle.

Runners, share you #ShamrockSelfie with NBC 5, and we'll add it to our gallery of photos.

Whether you're warming up, or even during the race, there's plenty of opportunities to snap a quick selfie. Just remember to email the photo to isee@nbcchicago.com, or tag your masterpiece #ShamrockSelfie or #chicagogram on Instagram.

And don't forget, all the cool kids are doing it!
