Mayor Rob Ford seems to be a fan of espressos.

In the latest installment of "Coffee Run," a YouTube show hosted by Deadmau5, the mayor is a guest on his online series.

Discussion about Ford's appearance on the show started in April when the musician tweeted at Ford, inviting him to participate. The tweet was followed up by a meeting on Monday when Joel Thomas Zimmerman – Deadmau5's real name – stopped by at Ford's city hall office. Previous celebrity guests on the show include actor Tom Green and singer-songwriter Pharrell Williams. In Wednesday's episode, Zimmerman picks up Ford in his famous blue Ferrari, nicknamed the "Purrari."

They head to a local Tim Hortons where they order their drinks at the drive-thru. Zimmerman orders an extra large double-double coffee and asks Ford what he would like to drink.

"Can I get five espressos in one cup…It's good, buddy. Trust me," Ford says.

Zimmerman laughs at Ford's order, and jokingly says that the mayor's caffeinated drink of choice is a recipe for "cardiac arrest."

Ford then pays for the drinks, before the two zip off and talk about everything from Tim Hortons being a "cash cow" to what's it like driving in the city.
