At a campaign rally in Hamilton, Ont., on Thursday, Conservative Leader Stephen Harper mocked the Liberal Party's plan to run a deficit.

Harper was cracking jokes, pinching his fingers and making gestures with his hands, all aimed at mocking Liberal Leader Justin Trudeau's proposal to run a "modest short-term deficit" during his first three years in office.

"He'll run, he says, a modest deficit, a tiny deficit, so small you can hardly see the deficit," a fired-up Harper said to huge crowd laughter.

"And only for three years, three deficits, three modest little deficits."

CBC first posted a photo of Harper's hand gestures on Twitter and people got pretty excited.

They started coming up with their own interpretations.

It's the latest meme-able moment on the campaign trial, following on Angry Old Tory, Middle Kid and Bathrobe Guy.

There have been some other quality Harper-themed GIFs floating around on the internet...

There's this one from the Macleans' leaders debate in early August, where Harper debated against Trudeau, NDP Leader Tom Mulcair and Green Party Leader Elizabeth May.

Finally, a gif that that fully represents my feelings towards most things. <a href="https://twitter.com/hashtag/stephenharper?src=hash">#stephenharper</a> <a href="http://t.co/TUXOC4qZPO">pic.twitter.com/TUXOC4qZPO</a> —@SharkRobotStore

...but the squeezing of the fingers might be the new contender for best GIF of the campaign.

Harper's not exactly known for being outwardly humorous and that caught a few folks off guard.

The Hamilton rally was decidedly relaxed compared to other Conservative campaign stops. Harper cracked jokes and interacted with a crying baby. His speech even sat on a music stand, instead of a podium.

I sincerely wish Harper allowed Canadians to see more of the funny side his aides and allies say exists. —@markusoff

Relaxed. Confident. Harper having fun. Do you think he knows something we don't? <a href="https://twitter.com/hashtag/elxn42?src=hash">#elxn42</a> <a href="http://t.co/vJAE0O1K4W">http://t.co/vJAE0O1K4W</a> —@StylesKe

Some thought his jabs at Trudeau were pretty sassy.

While Harper was clearly having fun, there were some on the internet who just weren't having it at all.

Is Harper really criticizing someone for deficit spending? His government hasn't seen a surplus since 2007. <a href="https://twitter.com/hashtag/elxn42?src=hash">#elxn42</a> <a href="https://t.co/p6dZ1qE62y">https://t.co/p6dZ1qE62y</a> —@detaylor

Just saw the .gif. Glad to see Harper hasn't lost his sense of humour when asked what % of the PMO didn't know about Wright/Duffy <a href="https://twitter.com/hashtag/cdnpoli?src=hash">#cdnpoli</a> —@Will__Murray

Harper, who promised Canadians he would never run a deficit and then ran a shitload, criticizes Trudeau for being honest. —@Ken_Donnelly

And while Harper's hand gestures were referring to the Liberal deficit, some thought they meant something else.

Looks like bed time stories w/ Stephen Harper? <a href="https://t.co/eUROkf7D7k">https://t.co/eUROkf7D7k</a> —@MSangiuliano93
