The Ministry of Home Affairs has officially designated the Singaporean Mother-In-Law as a Category 1 biological weapon.

Under the new "Mother Knows Best" directive, any female over the age of 50 is entitled to perform unannounced inspections of her son’s marital bedroom to check for thread counts and moral failings.

Experts claim this evolution is necessary to maintain the natural ecosystem of overbearing matriarchy that keeps the nation’s economy afloat.

"I tell her already, that fish must steam ten minutes, she go put twelve minutes, now my son eat like rubber," said local matriarch, Mdm Tan.

"The floor also sticky-sticky one, I think she never mop, only know how to spend my son money on handbag," she added while aggressively rearranging her daughter-in-law’s spice rack.

The government has confirmed that any daughter-in-law caught rolling her eyes will be sentenced to three weeks of intensive "How to Boil Soup" retraining.

Civil rights groups have remained silent, mostly because their own mothers told them to shut up and finish their bird’s nest soup.
