Let's get one thing straight: all Pronto Pups are technically corndogs, but not all corndogs are delicious enough to be Pronto Pups.
Assignment #134 in the 365 Things to Do in Memphis is to sample the noble Pronto Pup, Memphis' favorite food on a stick.
I'm not sure what it is that makes a Pronto Pup way better than a normal corndog. The breading seems to be a little thicker, the hot dog seems to be a little better, and the nice people at the stands use a brush to liberally apply a coat of mustard to the Pup's outer shell.
Or it could be because Pronto Pups have such a place in local history - the Andreini family has been serving their specially breaded hot dogs on sticks in Memphis since 1940.
The easiest way to try a Pronto Pup is to go to a local festival (think World Championship Barbecue Cooking Contest, Cooper Young Fest or the FedEx St. Jude Classic) and look for the yellow booths.
