The image had clearly been photoshopped, and showed the radio host looking noticeably wider than normal standing next to his co-host, Ryan 'Fitzy' Fitzgerald.
'Look at how f**king wide I look!' he yelled after a receptionist asked him to take a photo next to his blown-up likeness.
After being told the marketing department had mocked up the poster, Wippa fumed: 'They've done that deliberately!'
At this point, the radio station's female marketing director interrupted his outburst.
'Look at the f***ing size of me!' Wippa repeated, as the staff member tried not to laugh.
The staff ask, 'Do you want a photo with it,' to which a clearly irritated Wippa yells, 'No!'
The two female staff then burst into laughter.
