There's loads of videos of him on their show, straight up abusing Katie Price.
But in this video he mocks Harvey's disability.
He gets Harvey to say:
PA - 'I want that one'
(Harvey imitates him, wanting to please)
PA - 'Dont he look a bit Matt Lucasy eh'
KP - 'no he dont, hes my Harvey'
PA - 'he does a bit, just like that'
'He looks Matt Lucasy' refers to Matt playing a disabled man on Little Britain (vile show, vile men) who only has one phrase.
