bust vs arrest

0Capitalizing on Senator Larry Craig's restroom 01b00bust02b00, a Minnesota minor league baseball team this Sunday is giving away a promotional item celebrating the Republican politician's arrest last year at the Minneapolis-St.Paul airport. Dubbed a "bobblefoot" (as opposed to a bobblehead doll), the polyresin giveaway depicts an occupied bathroom stall (the 01b00inhabitant's 02b00pants and shoes can be seen below the stall's panels). 02br
