If the element Pb is Lead, does that make a Pb and J sandwich lethal?

never ask a scientist to make you a pb and j sandwich. while us common folk understand it as an abbreviation for peanut butter and jelly, the scientist, incapable of comprehending peasant speak, will instead give you lead (Pb)

J is the old symbol for iodine. So when he said “I’m going to have a Pb and J”, your mistake was answering “I’ll have a PbJ2”.

Pb = lead
