Non-Rapper Tupac Arrested In Drug Bust With Non-Actor Robin Williams

Robin Williams and Tupac smuggled a HUGE amount of pot through Arizona and got busted ... at least that's how this case reads at first glance.

Law enforcement says Arizona State Troopers arrested 19-year-old Tupac Crum and 21-year-old Robin Williams near the city of Payson after finding them with 114 pounds of weed during a traffic stop.

Cops suspected something fishy and brought out a drug-sniffing dog to check out their Chevy pickup ... and they say they found 5 big bundles of pot stashed in the bed. Cops say the drugs have a street value of about $69,000.

Fake-ass Pac and Robin face multiple drug charges.
