Yeah, Roswell, how ironic is that? They'll sure as hell not let you a legal citizen back in if you don't have your paperwork, but they're doing nada to enforce the borders...which in that circumstance will be OK.

Just bring a frizbee when you cross and sheepishly say, "Yeah I was throwing my frizbee and it went across the border, I went to fetch it and you happened to show up when I was coming back across. Apologies for any inconveniences."

Seems like it would work, but they'd probably give you to the Mexican government for infringing and illegally crossing their border, the putzes.
