O'Reilly Automotive is one of America's largest retailers of auto parts, operating well over 5,000 O'Reilly Auto Parts stores across the U.S.
A behemoth auto-parts chain is perhaps not one of the more likely places one would look to for wry humor, but the company's website does host at least one in-joke -- searching the site for part number "121g" turns up a listing for a flux capacitor, the device invented by Doc Brown in the popular 1985 film "Back to the Future" that enabled Marty McFly to drive a DeLorean DMC-12 30 years into the past:
The 121g part number, of course, refers to 1.21 gigawatts, the amount of power required in the film to activate the device:

The O'Reilly website also offers some useful caveats and warnings to potential users of a flux capacitor, including that plutonium (needed to create a reaction that generates the 1.21 gigawatts of power needed by the device) is "not available at O'Reilly Auto Parts," and that the flux capacitor "requires the stainless steel body of a 1981-1983 DeLorean DMC-12 to properly function":
- Time Travel at your own RISK!
- Plutonium is required to properly operate the flux capacitor
o Plutonium is used by the onboard nuclear reactor which then powers the flux capacitor to provide the needed 1.21 gigawatts of electrical power.
o Plutonium not available at O'Reilly Auto Parts. Please contact your local plutonium supplier.
- Flux capacitor requires the stainless steel body of a 1981-1983 DeLorean DMC-12 to properly function.
o Once the time machine travels at 88 mph (142 km/h), light coming from the flux capacitor pulses until it becomes a steady stream of light, at which point time travel begins!
Alas, O'Reilly also informs would-be time-traveling customers that "This item is not available for purchase" and that the listing pictures a "Non-Functional Item Displayed for Entertainment Purposes Only."
