Pat Flaherty and Jessica Denney in Mr. MarmaladeNew Ground Theatre's current offering, Mr. Marmalade, is about four-year-old Lucy and her imaginary friends. Suicidal, coke-snorting, physically and mentally abusive imaginary friends. And it's incredibly funny. One particularly dark scene during Thursday's performance, in fact, had me laughing so hard, for so long, that I was wiping away tears by the end of it.
