Someone needs to show House Speaker Paul Ryan (R-Wis.) what a real pint of Guinness looks like.

He held up an embarrassing excuse for what was supposed to be a pint of the black stuff at the Friends of Ireland luncheon in Washington, D.C., on Thursday, and immediately made Twitter users seethe with anger.

First Mike Pence says 'top of the morning', then Paul Ryan holds up this appalling pint, grave missteps by the US pic.twitter.com/U4ktqf0Aag — Naomi O'Leary (@NaomiOhReally) March 16, 2017

Some people took aim at its lack of a proper head, while others questioned just how long it had been sitting there before Ryan held it aloft.

@NaomiOhReally Here's Obama's pint for comparison. One of the many areas he excelled in. pic.twitter.com/gO7h9hG1r9 — Michael Dinerstein (@loudin) March 16, 2017

The tremendous amount of real estate at the top of that pint, probably pulled an hour before https://t.co/WasZmlloF8 — Emily Reily (@Radiobites) March 16, 2017

The pint's shadow is so embarrassed at how flat and useless it is, it's hidden itself. #StPatricksDay @NaomiOhReally #pintgate pic.twitter.com/IR5JY8REH2 — Fact Check #Apr8 (@IrelandUncut) March 16, 2017

Not sure about Pence, but Ryan has definitely given up any chances to be allowed to enter Ireland ever again... https://t.co/1oZxCU83fh — Matteo Lanzafame (@MatteoLanzafame) March 16, 2017

@NaomiOhReally Looks like he drained the swamp into that glass. 🤢 — Andy Cole (@ajcole180) March 16, 2017

@NaomiOhReally $5 says he's trying to pass Diet Coke off as Guinness. It's a lepre-con — Joe Hanson (@DrJoeHanson) March 16, 2017

@NaomiOhReally We'd sling that straight back if we were served something as ghastly as that looks....disgusting — polly dymock (@pollsstar) March 16, 2017

@NaomiOhReally On behalf of my countrymen and women, We're sorry.

If it's any consolation, Mr Ryan's political career is likely ending soon🍀 — Daniel Norman (@DreamingInCode) March 16, 2017

This is definitely a man who’s never had to hold a Guinness while watching his Premier League team break his own heart in a pub at 6am. https://t.co/ZwITP4rbvD — Damien Sorresso (@EBADTWEET) March 16, 2017

Paul Ryan has brought shame upon our flag. https://t.co/ZfWNLssYx4 — southpaw (@nycsouthpaw) March 16, 2017

@NaomiOhReally I've produced better pints of Guiness AFTER I've drunk them — Terry Fletcher (@Agedcragrat) March 16, 2017
