The 41-year-old, who works at a furniture store, claimed he found the bag in a dresser delivered to the store from California.
It doesn't end there, though.
Cops were suspicious and asked Barrios if they could search his house near Hylan Boulevard and he agreed.
They found more greenery under trees in his backyard: seven trash bags filled with around 50 pounds of marijuana in separate, vacuum-sealed bags.
Cops are stumped as to why Barrios initially handed over the 25-pound bag and gave them permission to search his house, the Post reported.
He and his 30-year-old wife, Kristine, were charged with multiple counts of felony pot possession and could be facing 15-year prison sentences, a spokesman for Staten Island DA Daniel Donovan said.
