A rough translation?
With the first girl Isabelle, Patrick basically told her that he wants to tickle them because a viewer wrote in saying that he wants to know who is the most ticklish VJ. Isabelle shot back saying essentially "Were you that viewer, since who else would want to touch all the VJs?" She then says that she's appropriately dressed for that and twirls (pity Isabelle isn't that ticklish). Patrick says "Are you willing to try?" and she says yes.
As she sits down, Patrick says "Are you ticklish?" Isabelle asks if it counts if she laughs, and he said yes (since the competition was to see who could hold it, which may explain why Isabelle was able to hold it so well.)
He gives the same challenge to the other 3 VJs, while Valerie (the one in the pink) declares that she's only ticklish in one spot (obviously a lie). She says "I won't say which; you have to find it." Patrick says we'll look for it, and she squeals.
The VJ in the black tee asks if the least ticklish VJ wins.
Then the tickling begins.
When he gets to Valerie at 1:54 (pink tank), she goes "Go ahead, I'm ready". Patrick goes, "Here!" Valerie says "No, that's the most ticklish spot!" Patrick then celebrates "I found it!" She tries to tickle him, and as she touches her own sides, she says it tickles so much there that it hurts. Then Patrick tells her how his grandfather used to get him, then he tells her he's going to try another spot.
More tickling happens.
2:32, the girl in the black tee says "I swear..." and Patrick says "I didn't even touch you!" When he tickles her knees, she whispers, "Ok that tickles!"
Isabelle in the meantime says she feels nothing, to Patrick's disappointment.
2:56 "Are you ticklish on the bottoms [of your feet]?" She says "Yes, a little. Yes! Yes! [giggle]" At 3:18--"Did you like your experience?" "I adored it."
To Isabelle: "Listen, I think you're going to win. You really aren't that ticklish."
To which she answers "Do I win a prize? A certificate of ticklingness?"
He answers "Hey, that's a good idea!"
3:50--"Thanks Valerie!"
"My pleasure, whenever you want."
"Ok. Here!" [she squeals]
3:56--"there were two who were really ticklish: you and Valerie."
"Oh Valerie, yeah. I'm also imagining that Valerie was like [imitates her laugh] really loud."
"But you were really aggressive! So who wins [most ticklish]? It's hard to say."
4:26--He decides that it's a tie between Valerie and Chelie(?--the girl in the black sleeveless--Francois would know the name).
4:42--"It was a great pleasure. Listen, you go to work one day and you get tickled...by Pat...Groulx!"
Ok, pretty rough translation, but it gives the idea. Hope that helps!
