Are we really surprised that a calendar full of buff, glistening, shirtless men in firemen uniforms holding adorable pups for the sake of charity turned out to be a popular idea? Nah-uh. And the fact that its launch party — featuring the same muscular fellas showing off their rock-hard abs and soft spots for puppies onstage at the Memminger Auditorium — was voted to be the best time in town last year also ain’t a shocker. The steamy calendar’s funds go to Charleston Animal Society’s Toby’s Fund, a medical fund named after a golden retriever who the nonprofit helped recover from serious chemical burns. In other words, a sexy party for a purpose is the very best kind — duh.
