"We'll be honest. We've spent all morning brainstorming ideas for a clever email to send you about 30330," Biden's campaign said in an email. "(In case you missed last night's debate, Joe meant to say "Text Joe to 30330" but left a word out. Oops.)"

During closing statements of the debate in Detroit, the White House hopefuls urged potential supporters to visit their websites and donate.

Biden, however, intended to direct supporters to text "Joe" to the phone number 30330.

Many members of the media joked about the misstep, and domain names related to the flub were bought up quickly.

While joe33030.com redirects to Biden’s website, Joe30330.com redirects to a page for what appears to be a satirical campaign.

In the email to supporters, Biden's campaign urged supporters to donate $3.03, $30.33 or $303.30.
