22 Minutes' Marg Delahunty Ambushes Conservative Senator Mike Duffy (VIDEO)

WATCH: Mike Duffy Ambushed

Marg Delahunty is back to ambushing prominent conservative politicians.

The alter ego of comedian Mary Walsh, who famously had 911 called on her by Toronto mayor Rob Ford, has a new target in tonight's season finale of This Hour Has 22 Minutes: Tory senator Mike Duffy.

After showing off her trademark sword, the 'Princess Warrior' heads directly to Duffy to ask him about the balls of his feet.

"I thought they had put you in the asylum by now," Duffy says, quickly.

It seems like a safe bet that Delahunty will have some fun with the embattled senator who admitted in late February that he improperly collected tens of thousands in housing allowances.

Duffy has offered to repay the allowance associated with his Ottawa home, but the episode proved embarrassing for the so-called "house of sober second thought."

This Hour Has 22 Minutes airs on CBC TV Tuesday nights at 8:30 p.m. Catch more clips of the show on Facebook and Twitter.
