This guy may very well have the worst hangover ever.

In this video, a man appears to drink an entire bottle of Jagermeister through a funnel. While he seems to do it with relative ease, we really wish the camera remained on so we could see him try and walk and keep his insides inside an hour or so later.

His effort was quickly topped in another similar video (note the NSFW language) by an Australian woman who guzzles an entire bottle of Jagermeister, as part of some trend called #Neknomination, in which you must polish off a bottle of liquor after someone chooses you.

Ahh, peer -- or is that beer? -- pressure.
