I'd guess we should have expected something like this eventually...I LOVE "HOT-TUNA"... the band ..not the sea fare that can turn you into a glowing object ...S C A R Y to say the least ...I wonder what those guys on "Wicked Tuna" have for opinions on this matter. I can only guess someone here will say they'd eat it anyways. . . "blah-whats a goiter the size of a football...I'm never going to stop eating tuna"...ya gotta know it's coming . . .hahahaaa
