(Newser) – Gary Johnson had what he called another "Aleppo moment" Wednesday night when he was flummoxed by the question, "Who's your favorite foreign leader?" The Libertarian presidential candidate, speaking at a televised town hall event at the University of New Hampshire, didn't have a ready answer but got more time to think when running mate Bill Weld said his was Shimon Peres, only to be told by MNSBC host Chris Matthews that it had to be somebody living, ABC News reports. "You got to do this. Anywhere. Any continent,” Matthews told Johnson. "Canada, Mexico, Europe, over there. Asia. South America. Africa. Name a foreign leader that you respect."

"I guess I'm having an Aleppo moment ... the former president of Mexico," said Johnson who wondered, "What is Aleppo?"—or possibly "What is a Leppo?"—when asked about the Syrian city earlier this month. CBS reports that when Matthews asked which former president of Mexico he was talking about, Johnson said he had a "brain freeze" and Weld eventually helped out, saying "Fox," for Vicente Fox. "Fox! Thank you," said Johnson. "He was a terrific leader." After getting Johnson off the hook, Weld went on to name German Chancellor Angela Merkel as the living leader he most admires. (Johnson says the Libertarian ticket is the only one "that offers Americans a chance to find common ground.")
