It takes a lot to make a pug unfunny. With a squashed face, bulgy eyes and oddly dainty legs, a pug is a natural comedian -- especially if he is the pug from the first Men in Black movie. MIB fans may remember him as Frank, the gravelly-voiced, smart-mouth alien masquerading as a dog. In the first movie, he was a brilliant little side joke, a throwaway gag. In the second, he makes an extended appearance -- but in this case, more is not better. In lieu of showcasing new material or a coherent plot, the creators of MIB have decided to trot out old jokes like Frank over and over again until even he, chock full of charm, wears out his welcome.
