On the last day of his Mexican vacation, Neil Patrick Harris took to Instagram on Jan. 6 to share photos of a margarita-filled afternoon. 

Harris provided himself with a margarita challenge, which he simultaneously accepted.  The 8-part photo display shows the How I Met Your Mother actor by pools, beaches, and bars.  Each picture was also tweeted out with a caption to match.

The first Instagram photo is captioned, "Last day of our Mexico adventure.  Let's just see how many Margaritas I can drink.  Cheers!"

From that point on, things seemed to escalate rather quickly, as the 40-year-old can be seen partying hard, passing out harder, and even staring at a blender full of margarita.  

Fans quickly showed their support for Harris' social networking venture, as likes and comments added up into the thousands.  One fan commented, "You flicking rock! I love how funny you made all this."

Harris can be seen on the small screen when CBS' How I Met Your Mother returns on Monday, Jan. 13 at 8/7 p.m. Central. Be sure to keep checking back with Enstars for more of the latest information on Harris and the popular sitcom.
