The Great Allentown Fair has everything: pigs, rides, cars smashing into each other, every type of food you can imagine and more. This year, you can add puppets to the list. Comedian and ventriloquist Jeff Dunham is headlining the Allentown Fair’s grandstand on Sept. 1, joining Brad Paisley and Pentatonix on the slate thus far. Dunham, who at this point qualifies as a veteran of the fair, will be making his fifth appearance at the grandstand and first since 2016.
