A conversation, verbatim, between my brother and his roommate, in the cafeteria of that venerable instituion of intellectual learning, UCLA:
"Dude, that's nasty!"
"Dude, it's a tuna melt."
"Dude, I had it before and I yakked."
"Dude, all tuna tastes the same."
I have to side with my brother on this - I can't really tell the difference between one can of tuna or another. Foodgoat can, though (he's got "the touch").
Then again, what do I know about tuna? I was quite surprised to learn that tuna fish are huge. Because you know, the cans are tiny.
