The Raptors saw an estimated 1.5 million people flood the streets of Toronto on Wednesday for the team's first NBA championship parade.

Tom Brady's reaction? Challenge accepted.

Here's the New England Patriots quarterback's simple yet effective tweet upon seeing the massive turnout in Toronto:

Brady knows a thing or two about highly-attended championship parades: Roughly 1.5 million people came out in Boston just four months ago to watch the Patriots celebrate their sixth Super Bowl title.

That attendance number was a record for the city's many Patriots title parades, but it appears the Raptors matched that Monday.

So, Brady and Co. will just have to win a seventh championship to raise the bar yet again next February.
