Looks like Mariah Carey has at least one thing in common with Dane Cook—aside from utter humorlessness.

Like the supposed “funny” man, Mimi is accused of not picking up her doggy droppings. According to the New York Post, the singer’s two pooches made a drop-off outside the Roberto Cavalli boutique on Madison Avenue in New York…and FAILED…TO…SCOOP!

Looks like Carey’s beleaguered boy-groom, Nick Cannon, is slipping in his duties. Such tasks are clearly in his bailiwick.

Nick better step into line; Mimi’s not above doling out pink slips at the slightest provocation.
