I don't know about the
pinktaco eating contest, but the rest is legit -
Charlie Sheen-co de Mayo.

The Lake Elsinore Storm Professional Baseball Team today officially invited actor Charlie Sheen to participate in a different kind of rehab, one that will recognize the former on-screen pitcher and star of "Major League" with a "Charlie Sheen-co de Mayo" promotion.
This special occasion, held on May 5, 2011, is fittingly a
Thirsty Thursday promotion featuring one dollar beers and Coke products. On this festive night, fans can expect a full slate of fun to highlight the antics of the beloved star of "Two and a Half Men."
Mr. Sheen, his entourage and "goddesses" are formally invited to attend this night of baseball, Charlie and fun. Pregame plans for the Charlie Sheen-co de Mayo Night include a
limited edition bobblehead immortalizing the Hollywood icon, a "Wild Thing" glasses giveaway as well as retiring, for the season, his number 99 from his legendary role as closer Ricky Vaughn.
Other promotional elements will include an
in-game taco eating contest, a Rehab-style party on the exclusive Tiki Terrace featuring #tigerblood cocktails and a two-for-one Ho Hos special.
"As with any rehab assignment, we're here to help Charlie embrace that '#winning' feeling," said Chris Jones, Vice President/General Manager of the Storm. "Also, as a show of support,
we welcome all current cast and crew members to the ballpark that night for only two and a half cents."
