Neil Patrick Harris’s Hilarious Mexican Margarita Adventures!

Never forget that Neil Patrick Harris is a comedian.

The "How I Met Your Mother" star went wild — or at least he pretended to — during his vacation in Mexico with his family, fiancé David Burtka, son Gideon, 3, and daughter Harper, 3.

The 40-year-old actor began his fun-filled adventure on Monday by Instagramming a pic by the pool: "Last day of our Mexico adventure. Let's see just how many margaritas I can drink. Cheers!" he wrote.

And the fun continued to roll on for the Emmy winner, who managed to rack up an impressive amount of funny pics — and tasty frozen cocktails — for the day. An hour after he posted his big idea, he shared a snapshot of himself on the bed. "Margarita #4: Feeling great. Can't find my book..."

Nearly two hours later, he posted another pic of himself with the caption, "Margarita #12: I's the life of the party!! Everybodyone is LOVING me!!" Judging my everyone's faces in the (totally staged) photo, it's safe to say they did exactly agree. And the silliness just escalated from there…
