A gal can always use a good guffaw, and Ladies Laugh-In makes sure that she can get it at least once a month. Comedians Heather Snow and Chella Negro are the hostesses of the monthly showcase at Beauty Bar, and while the featured performers are mostly women — everyone from Lori Callahan to Nora Lynch to Alicia Jacobs — there are often a few men in the mix, too; both Adam Cayton-Holland and Ben Roy have joined the ladies on stage. Now in its second year, Ladies Laugh-In is not only a guaranteed good time, but it benefits a good cause: A charitable component has been added to the show, with suggested door donations going to various nonprofits each month.
