Well--maybe better to leave to the imagination what would be in a "GG Sandwich."
Forsooth. Obviously you are referencing human excrement. In reality, G.G.'s cupboard would contain much more variety than you suggest. Please cease and desist with the simplistic fecal obsession.
Just a few items in G.G.'s culinary repertoire:
Jim Beam- "Hangin' Out With Jim"
Peanut Butter Sandwiches and Whiskey- "Outlaw Scumfuc"
Hard Candy- "Hard Candy Cock"
Rectally Discharged Hotdogs- "Hated"
Meat- "Young Little Meat"
Maize- "Cornhole Lust"
Leftovers- "Eat My Leftovers"
Secret Ingredient- "Drink From The Pissing Snake Mouth"
...now if you posit that Elvis was the proto-bacon sweets innovator, things get interesting. Inappropriate bacon creep is now acceptable to the American palate- bacon candy bars, bacon pie, bacon lollipops etc. Let your imagination run wild. What if G.G. took Elvis' place? Can you imagine the wacky menu items one could sample at the Wisconsin State Fair. Think G.G.-style cheese curds...
