Don't feel silly! These are a guilty pleasure of mine too!
Here is where I have found them...
The BBQ Shop at the Sunshine Season Food Fair in the Land in Epcot. They have them as a kids meal for about $3.50.
Cosmic Ray's in Tomorrowland at the Magic Kingdom also serves corn dog nuggets as a kids meal for abut $3.50. Comes with fries and they did not look at me funny when I ordered it.
The only other one I have found is the Boardwalk to Go Kiosk. It's right across the way from Spoodles. They have a pretty good corn dog there also for about $3.50. You can add fries and a drink and it would be $7.50. This was my favorite but the hot dog took a bit of getting used to. It was very pale... almost like a chicken weiner, but good!
I have heard rumours about a corn dog at Pleasure Island but I don't have any info...
Enjoy!
