From "The Onion"…'SCIENTIST HAS NAGGING FEELING HE LEFT PARTICLE ACCELERATOR ON'
"Chicago - University of Chicago particle physicist Matthew Sharp drove halfway home before he was struck with the fear that he'd left the Argonne Tandem Linac Accelerator System running…'I think I powered it down after smashing those 9-GeV electrons into 3.1-GeV positrons, but I don't specifically remember flipping the switch,' Sharp said.
'Not only does a nine million volt electrostatic tandem Van de Graaff injector accelerator cost a lot to run, it's also a pretty serious fire hazard.' Sharp almost turned his car around, but didn't, because the past three times he's gone back to check on the accelerator, he's found it off."
