Jasper T Jowls

Jasper is commonly portrayed as a rather goofy redneck dog. In the days of the Pizza Time Theatre, he would uncontrollably laugh at almost any joke, much to the major annoyance of Chuck E., who would often shout "Turn off the fruitcake dog!", which would prompt the backstage technicians to supposedly turn off Jasper, which would stop his laughter and calm him down. On rare occasions, though, Jasper would be so depressed that he couldn't "get his laugh going", prompting the others to try and cheer him up. PTT Jasper was also known for becoming infatuated with most of the Guest Stars, often flirting with them, dedicating songs to them during shows, or simply breaking out in bouts of “lovesick bugling” whenever they were around, much to Chuck’s chagrin.

As the years went by, Jasper's personality became calmer and more laid-back, and his wit became much sharper, especially when having conversations with the other members of Munch's Make Believe Band; he gets into disputes with Pasqually over his eccentric ways and jokes, teases Chuck about Helen’s crush on him, and reprimands Munch about his obsession with pizza. Although he can sometimes come off as cynical, Jasper means well and is always friendly to a fault.
