Brendan Schaub's justification for adding blackcurrant to Guinness not being well received

Brendan Schaub, you're out of your element here.

Former UFC heavyweight Brendan Schaub came to Dublin earlier this year to bring his Big Brown Breakdown podcast on tour.

When he hit the Irish capital he managed to do something quite remarkable - win over the locals through comedy while sending them into a rage with the first pint he ordered.

"I looked this grizzly Irishman in the eye who's family fought off the English in this bar and it's been family-owned forever, I said, 'Three purple Guinness, please, sir! He goes, 'Are you sure?' and I went, 'Yeah.' He goes, 'Alright', and then gives them to me. I had no idea that you were not supposed to do that."

Despite the public outrage confirming how wrong he was about adding blackcurrant to Guinness, Schaub is still banging the same drum.

He attempted to justify his decision again this week by reposting an Instagram photo from Guinness US trying to promote their new drink that caters towards poor souls like Schaub who were born with a tastebud deficiency.

Me hole, Brendan.

Me hole.

Firstly, it's not called a 'purple sour'. It's not called anything because it's not a real drink.

We know it, you know it and your hordes of Twitter followers know it too.

Ah...it's not really Guinness though is it. It's like comparing UBEReem and Overeem...#SkepticalHippoTastebuds — Joseph Corbally (@joecorb88) November 18, 2017
