If you've watched How I Met Your Mother you know how dangerous a slap bet can really be. In Toronto, doubles partners Mate Pavic and Oliver Marach risked it all to play a game of table tennis for a slap. 

The world No. 3-ranked Pavic had the early lead in the game to five, leaping to 4-0. Somehow, his Austrian partner clawed his way back and won the sudden-death point for 5-4. It was quite the player lounge spectacle. 

And the slap? It was nothing like Barney Stinson's turmoil, but still did the trick. Pavic and Marach, the top seeds at the Rogers Cup, are through to the quarters after Grigor Dimitrov and David Goffin withdrew on Thursday.
