Joe Biden on Thursday laughed off his flub at the end of the second Democratic debate, saying he should have said the word 'text' in his closing statement.

'Instead of saying "Joe," I would have said "text." I was so focused on making the case for Joe, I said "Joe" and I gave the number. It was text so I would have changed that,' he told reporters at an event in Detroit.

He also thanked the media for covering his mistake and said the gaffe was giving his campaign 'great results.'

'But you guys have printed it 15 times and it's getting great results for us. We've had a lot of incoming because of it,' he added.

Biden's campaign sent out a fundraising email based off his gaffe

The former vice president blundered his own promo at Wednesday's night Democratic debate, mixing up his web address with a number to text.

His campaign also sent out a fundraising email to supporters with the subject line 'Joe 30330.'

'We've spent all morning brainstorming ideas for a clever email to send you about 30330,' the note began.

His team then invites supporters to donate $3.03, $30.33, or $303.30 to the campaign. And the note ends with this suggestion: 'P.S. If you're reading this on your phone, text Joe to 30330.'

Biden's flub came in his closing remarks, when the 76-year-old asked supporters to 'go to Joe 3-0-3-3-0 and help me in this fight.'

He left out the word 'text' - as in supporters were supposed to text 'Joe' to the number.

Biden had endured a night of heavy attacks from his rivals on the debate stage and his campaign quickly tweeted the correct way for supports to show their support.

Internet pranksters pounced at Biden's mistake, snatching up the domain name and redirecting Joe30330.com to a fundraising page for his rival Mayor Pete Buttigieg

Joe30330.com soon led people to a website for 'the first Gen Z'er to declare candidacy for office'

'If you liked what you heard tonight, text JOE to 30330 and let's get to work,' Biden wrote.

It was later changed to redirect people to joshforamerica.com, a website for 'the first Gen Z'er to declare candidacy for office,' who says he is ‘not joshin’ you’.

Biden also showed his age when he used one of his favorite old-fashioned words in the debate - 'malarkey'.

Twitter users poked fun at the presidential hopeful's slip-up.

'The internet is hard,' someone wrote with a clip of Biden's blunder.

One person posted a picture of someone trying to decipher complicated calculations with the caption: 'Me trying to figure out Joe Biden's website.'

'Love that Joe Biden trusts us enough to give us his pin number,' quipped another.

Someone else wrote: 'Joe Biden right now' with a picture of a man saying 'What's a text?'

'JOE30330??!!! GO THERE?! HOW JOE?! HOW TO I GO TO JOE30330?!' a confused Twitter user wrote.

Others struck a more serious note.

'How is Joe Biden going to take it to Trump when he can't even take us to his website?,' one person tweeted.

Someone else commented: 'Pretty harsh to mix up a text number with a web address, especially in his closing statement... especially at the end of his closing statement.'

Biden similarly stumbled as he gave the number for supporters to text at his campaign kick-off speech in Philadelphia in May.

'If you want to be part of this campaign, pick up your phones... Send a text to the word 'United' to the number 30330. OK? That's 'United' 30330. Or 303330 or 300 … but you got it. It's on the back there,' he laughed.
