Just call for a mammoth illegals picnic in Indiana or Kansas somewhere.
Plan it for several meadows and fields and open spaces to east and west. Build it and they will come. They’ll bring their baby buggies and grandmas and grandpas. They’ll pack their lunches and some of them will sell weed on the side.
Then when they’re all there yelling and screaming for legitimacy, Mayor Daley in the center of the pack can drop a huge net from the sky down over all of them.
Scoop them up in that net and haul them off through the clouds, dropping them in Brazil somewhere.
