Party till you puke … on a Monday. (Evy Mages/for TWP)

Because nothing says Happy Columbus Day like an epic hangover, feel free this weekend to make use of the District’s newly but slightly liberalized alcohol laws. The Post’s Tim Craig reports that 42 bars have applied to remain open till 4 a.m. in the wee hours of Monday’s holiday — as well as New Year’s Day, Memorial Day, Independence Day and Labor Day. (Bars still have to close at 3 a.m. on Saturday and Sunday morning.) It’s unclear how many of the 42 will actually be open late this weekend, but feel free to drop by Haydee’s, Jimmy Valentine’s or Dangerously Delicious Pies at 3 a.m. to figure it out.
