MADISON HEIGHTS, Mich. -- Detroit Lions quarterback Matthew Stafford peered through a slot in a hidden door on a Tuesday in September, protected at a local Meijer by a large, large display of Pepsi cans.

He was in full jersey, trying to catch unsuspecting customers by surprise as part of an ad campaign for the cola product as part of the Pepsi Can Cave. The concept was something Stafford enjoyed and created a line outside the Meijer once people found out what was going on.

"I've been doing some Pepsi stuff for quite a while now," Stafford said. "Got to do a Barry Sanders spot a couple years ago. Did a Grammy halftime show last year with a bunch of guys.

"So I've been working with them for a while now. Just another opportunity to do some fun stuff, do some fun video stuff, got to do it in Detroit with fans here, so that's always a plus."

The result is an ad dropping Tuesday from the Can Cave, with fans showing up inside and getting to theoretically party with Stafford for a few minutes.

Stafford has always appeared to enjoy doing these spots and he's a pretty good sport about it.

"It's a blast. It's super fun. Get to hang out with fans," Stafford said. "They are totally unsuspecting of what's going on and being able to surprise them, a regular Tuesday turned into a pretty fun one through Pepsi and the can cave, it was a blast."

Here's an exclusive preview of the commercial, coming out digitally later today.
