"It was pretty unbelievable," Kane told Leno about scoring the Cup-clinching goal against the Philadelphia Flyers. "It's every kid's dream to actually do that.
"It's a great feeling to bring the Cup back to Chicago."
After showing a replay of the clearing attempt against the San Jose Sharks in the Western Conference finals that hit Keith in the mouth and knocked out seven teeth, Keith presented a necklace with a tooth on it to Leno.
"When I found out I was coming on the show, I put this together for you," said Keith, who added that he has a lot more dental work to do and a dentist appointment on Wednesday. "I'm on a liquid diet right now."
Toews was shown a replay of being presented with the Conn Smythe Award as the MVP of the playoffs. As he accepted it from NHL commissioner Gary Bettman, the fans in Philadelphia booed.
"We knew they weren't going to cheer for us," Toews said, "so the booing was more a compliment to us than anything."
The Hawks then presented Leno with his own jersey before they sat in with the band.
The Blackhawks also made an appearance on ESPN's "SportsCenter" in Los Angeles later Monday.
