Andrew: "Woah Brendan that's a lot of fish you caught!" Brendan: "Yeah nucka.... Hey, one jumped out of the bucket! Grab him Andrew!" Suddenly: BLORT!!! Andrew and Brendan: "Fuckin' Robert, you didn't have to step on him so hard, you twadge!!
This actually is a BLT(Bacon, Lettuce, Tomato) with the addition of onion and sliced radish. That really makes a classic sandwich a real taste treat!. Bacon, Lettuce, Onion, Radish, and Tomato sandwich or BLORT!!
