A man, a pub and a dare

A man goes to a pub for a drink and spies on the counter a glass jar filled with $50 notes.
"bartender, what's this then" the man asks while pointing to his favourite ale on tap.
"oh, that's for the local dare we got set up, put in $50, you do three things and you get the whole jar. First you have to knock out the bouncer at the Pink Panther club down the road, big mean Maori bloke. Next we got this wild dingo out back, angry bugger, got to pull out one of its teeth bare handed. Finally up stairs me Nan needs a root, she's 98 but she's up for it" the bartender replies while pouring.

The man downs his glass, puts the money in the jar, nods his head and leaves.

20 minutes later the bartender gets a call from his mate at the club saying some crazy bastard knocked out the big kiwi bartender with an uppercut.
The door then slams open and the man walks in with a triumphant grin.
"Alright, where's this dingo? "
"The dogs out back tied up. Careful though it's pretty dangerous" says the bartender while opening the back door and showing him the way.
When he returns the pub is quiet, every patron listening in for the chaos that would come.

Then, squeals and screams, the sounds of tearing clothes and flesh.
The dingo was clearly ripping him apart and all everyone could do is sit there in dread, glancing at each other in worry.
A little while passes and it goes quite, until the back door slams open and there stands the man, panting and tired with bite marks and blood all over him.
"Jesus Christ mate" gasps the worried bartender, "no one's ever gone this far before".
The man stares the bartender down.
"I don't want to talk about it, just show me where your bloody grandma is so I can pull out her damned tooth".
