We Didn't Say That

Spanish can distinguish between singular and plural with verbs only.  No subjects necessary:

"Are there monsters under my bed?" 
 "Maybe yes, maybe no." 

 "Is that a definite yes?" 
"We didn't say that."

 "We?" 
"I meant to say I."  

"Uh...If there were an I. Right." 
 "Shut up, Wilson." 
 "Fortunately, monsters aren't very bright when they're hungry."

Notes:
Quizá and quizás are both regional variations for the word maybe.
Listo means ready, but also bright or clever.
