Bill Belichick may be needing a new email address after his most recent appearance on ManningCast.
The former New England Patriots head coach suffered an age-old blunder when he joined Peyton and Eli Manning on their ESPN alternative broadcast of Monday Night Football this week.
During the Week 12 matchup between the Los Angeles Chargers and Baltimore Ravens, the 72-year-old performed an incredible dad move when he accidentally flashed an email exchange of his notes to the camera.
The legendary NFL coach had printed out an email chain from his Gmail account that was titled, 'ManningCast Questions,' seemingly in order to help him prepare for the program.
NFL fans were naturally quick to mock Belichick with many trying to decipher his email address from the blurry screen grab.
'Belichick printing out Gmail exchanges that say “Manningcast Questions” is the oldest move in old head history,' one social media user shared alongside a screenshot of the moment.

'If high def you could see what his email address was,' another claimed, while a third asked: 'Anyone figure out what that email address is?'
'Bill Belichick with the ultimate old-guy move on the Manningcast - Printed out emails,' one joked.
Others blamed the gaffe on Belichick's age with one posting: 'Straight outta the boomer playbook.'
'Dude definitely still prints out his driving directions with Mapquest,' another chimed in, referring to the online web mapping service that predated apps such as Google Maps and Apple Maps.
Meanwhile, a couple of other social media users were surprised Belichick wasn't using another older online service.
'Surprised it’s not an aol account,' one said, while another agreed, adding: 'Anyone else notice Belichick is up with the times and is a Gmail guy? I thought for certain he’d have an AOL or Hotmail account.'
'Belichick's old-school charm! Print or perish,' another sympathized, suggesting Belichick's retro approach added to his personality.
Some were quick to bring Belichick's 23-year-old girlfriends Jordan Hudson into the jokes, questioning why the tech-savvy Gen-Zer wasn't assisting the NFL veteran with his technological troubles.

'His tech aged gf couldn’t help the poor guy out,' one social media user shared.
'Do you think his girlfriend helped him figure out the printer?,' another questioned, while a third echoed, 'His mid-20s girlfriend couldn’t help him out with this?? lol.'
The email appeared to be from an address belonging to Matt Patricia, who previously worked under Belichick as the Patriots' defensive coordinator from 2012 to 2017.
And some eagle-eyed fans zoned in on the sender address with one bewildered user asking: 'Does that say “From: Matt Patricia”'
'The fact that the email is from Matt Patricia is just icing on the cake,' another quipped.
'Matt Patricia forwarded the Manningcast Questions to Bill Belichick,' a third chimed in, 'Man is a secretary.'
Belichick has been making regular guest appearances on ManningCast this season as he continues to delve into the world of NFL media.
Despite being notorious for shunning the media during his days as the Patriots head coach, Belichick has added a number of new gigs to his resume since leaving New England, where he spent 24 seasons, in January.
In addition to ManningCast, Belichick also appears weekly on ESPN's Pat McAfee every Monday.
