The dwarf whose clothes were burnt in an AFL Mad Monday debacle claims St Kilda player Leigh Montagna refused to pay for damages.

Montagna's teammate Clinton Jones has apologised and will pay $3000 to a charity after he burnt Blake Johnston's clothes with a lighter in a prank that went horribly wrong.

Johnston, an entertainer known as Mr Big, said Montagna had hired him and a colleague to work at the Saints players' Mad Monday function this week as fake security staff.

After Jones burnt him, Johnston said he sent Montagna an email and asked for the burnt clothes to be replaced.

In an interview with Nine Network's A Current Affair, Johnston said Montagna rejected the request.

According to Johnston, Montagna replied in an email: "If you actually followed your job description and said you would entertain us, I would be happy to.

"But to sit on a seat and drink water for two hours and still want your money does not constitute work in my book.

"I am sorry if you felt your clothes were affected, but I also feel ripped off that I paid you money to entertain and you did not make any effort to try and entertain.

"If you felt we were disrespectful, you should have told me when I asked, but you said everything was okay - so I believed you."

Johnston added he was not injured in the prank, but was frightened and disgusted.

"All I could feel was a hot sensation on my backside," he said.

"I went to turn and then there was this smoke just coming off me ... it was really thick smoke.

"I could be in a hospital right now.

When asked what he thought of Jones, Johnson said: "I'm half the size but, really, I'm twice the man."

Johnston also criticised AFL chief executive Andrew Demetriou, who initially laughed on television when asked about the embarrassing incident.

Demetriou later rang Johnston to apologise.

"Here's the head of the AFL, on a serious matter, and he's having a chuckle about it," Johnston said.

"The phone call I received, he was really sorry - what he did was silly and what he did was wrong."

Demetriou later blasted the Saints, saying: "We spend our whole lives teaching children not to play with matches."

Johnston said his burnt clothes are with police.
