Bad Science Joke

And now we find out how many people are actually still checking this thing after being idle for so long...

Two biology grad students walk into a bar.

"Ok, now remember: if an if/then proposition is true, then its contrapositive is also true," says the first.

"Uhh...contrapositive?"

"Okay, an example: 'If a cell is E. coli, then it must be Gram negative.' The contrapositive would be, 'If a cell is not Gram negative, then it cannot be E. coli.'"

"Ohh, of course," says the second. "Quite obvious. Entirely bacteriological."


:-D
