You've Got Spam

Zoom back to the year 1960, a friend of yours calls you and tells you that he went to his inbox (the one at posta) and found that someone had sent him spam. Here is how the conversation goes:

"Hi, just got some spam sent to my inbox"
"What? Who would do such a gross thing?"
"The usual suspects"
"I really wonder what method he used while getting it, how he had the guts to wrap it properly and even more guts to send it to you."

Well, according to this conversation, the two guys are obviously talking about two different things.

Fast Forward, to the year 2006, and the same conversation would mean a different thing, now that we know what spam really is.

But, wait a minute, the largest of the toothed whales happens to be the sperm whale. It was named after the milky-white substance spermaceti found in its head and originally mistaken for sperm.

During mating, sperm whales lose quite a huge chunk into the sea, could that be the reason the sea is salty!
