Yo momma so stupid she stepped on ten cents at the 'march of dimes.'

Yo momma so stupid I caught her looking over a glass wall 

to see what was on the other side. 

Yo momma so stupid she thought a hot meal was stolen food. 

Yo momma so stupid she bought a solar-powered flashlight. 

Yo momma so stupid she spent twenty minutes staring 

at the orange juice carton because it said "Concentrate".
