The Guardian collaborated with Tumblr to live-gif the vice presidential debate on Thursday night. The breakout star? Joe Biden's face. Here's the best Biden reactions, naturally presented in gif format.

Chuckling

The debate begins and the tone is apparent early. Ryan is sober and serious. Biden, who was unmuzzled backstage by a desperate Obama, looks like a kid on Christmas.

Disbelieving



A remarkably poised Ryan pretends not to notice as uncle Joe informs the young buck to get off his lawn.

Eulogising



If this is how Biden acts when he talks about Medicare, imagine the vice president at a beer summit. Be honest, who would you rather party with?

Laughing



Biden's teeth. That is all.

Frowning

You're so wrong I can't even smile right now.

Sobering

The debate ends with the vice president in utter disbelief as his challenger prattles on about the budget or something.
