How I Met Your Mother's Neil Patrick Harris took a jaunt down to Mexico over the holidays, and the actor closed out the trip in a playful - and well-documented - haze of margaritas.

Harris, who will soon tread the boards on Broadway in Hedwig and the Angry Inch, stopped by the Ellen DeGeneres Show on Thursday to discuss his recent alcohol-related, end-of-vacation Instagram spree.

"I did, the last day, do this funny Instagram runner where I Instagramed a bunch of pictures of me the last day saying, 'Lets just see how many Margaritas I can drink, just as a joke," Harris explained to guest host Ellie Kemper, who was filling in for the flu-ridden DeGeneres.

The host flashed pictures of Harris is varying states of inebriation, but left off the 40-year-old's amusing captions.

"Last day of our Mexico adventure. Let's see just how many margaritas I can drink. Cheers!" wrote a shirtless Harris as he stood poolside with his first drink of the day.

As the hours passed and the empty glasses stacked up, however, Harris' tweets took on a less coherent nature.

"Margarita #12: I's the life of the party!! Everybodyone is LOVING me!!" the actor typed mid-way into his adventure before crashing facedown in the sand for his final message. "Magachita #3, 4 mebbe? : Bruuuglah dret scruh nuu rezzlooshun! Nigh nigh nowh. #annndblackout."

Looks like Harris took a leaf out of Barney Stinson's book and made the trip legen - wait for it - dary.
