In New Orleans, the good times are rolling all the way down the drain.

The city has pulled a whopping 46 tons of Mardi Gras beads from clogged catch basins in a massive cleanup effort that took four months, cost $7 million and required almost two dozen vacuum trucks, according to the Times-Picayune.

The colorful plastic necklaces are typically flung from windows and Carnival parade floats — sometimes in exchange for women flashing their breasts — and were all found along the procession routes, the paper reports.

In future Fat Tuesday festive seasons, the city plans to put guards on gutters to stop the beads from reaching the sewers, and will train locals how to clean their own neighborhood catch basins, according to the report.
