MONICA Lewinsky is now a cartoon character. In “The Alcoholic,” a new graphic novel by Jonathan Ames and Dean Haspie, a booze-addled writer meets the Portly Pepperpot at a book reading. “I tried not to, but I couldn’t help myself – I stared at her mouth,” he explains. As the two dine with friends at Veselka in the East Village, Lewinsky ogles a plate of kielbasa. “When she said the kielbasa looked delicious, it was like all the sound drained out of a very noisy restaurant,” the character says. “The whole table went into collective shock. We all thought the same thing: ‘Monica thinks that [bleep] looks delicious!’ ”
