SPECIAL TUESDAY GRAMMAR RODEO (WHOPPERS JUNIOR DIVISION): Those of you with long memories will note that today's Mardi Gras marks the 10th such celebration since Philadelphia's 2001 Mardi Gras riots, chronicled on our pages in 2003 and preserved on YouTube as well.
But I couldn't help but wonder: what's the plural of Mardi Gras? If I wanted to say "I still can't believe what happened ten [MGs] ago," what term would I use? Mardis Gras? Mardi Grases? Something else?
