Passing rest of url on as parameter

I’m just starting to wrap my head around passing custom parameters in page templates to WP but as my middle name should be “SucksAtRegex”, how would I tell WP to pass everything after examplepage to WP as one variable.

E.g. examplepage/123/12/2 would end up passing ‘/123/12/2’ as the mypath variable. I can then explode that in PHP and deal with it accordingly. I already use this method outside of WP, but I’m looking to move to WP as my CMS.
