Joke of the decade….

Two white lab rats meet in the pub after work.

“Evening Jeff. How’s life at the University?”

“Pretty good Larry. In another placebo group?”

“Yeah. Doing all right. You?”

“Life at Pfizer is nice. Great working conditions. You should come into the private sector. Much better deal.”

“I’m not so sure. What about all those dodgy vaccines they keep telling us about?”

“I wouldn’t worry if I were you.”

“Why not?”

“They haven’t finished testing them on humans yet.”
