Being buried in mecca

Alright this isnt really my joke, its a scene from the show Little Mosque on the Prairie. Yasir is at a cafe arguing with some people about how muslims are buried facing mecca. Fred the anti muslim guy was listening in and jumps in saying

So, what happens if someone croaks in mecca. What direction do you bury him facing then?

Yasir thinks hard for a moment and then geos

“Downtown!”
