Equivocal 'Barb's

‘Barb’s the word! Equivocal. E.g., here's three plus three.  
One’s Bobbie and the Riders of his (Benson's) B-Bar-B. 
Two’s Zanzibar, between the Wami delta and the sea.  
Inhuman "Butcher" Barbie’s three. (Klaus? No one's cup of tea.)  
Valeria Lukyanova’s four: a human Barbie, she.  
Five’s Donald! Donald tweets his barbs. (Don shuns all repartee.)  
Six? A rabbi goes into a bar because he needs to pee.  
See? Some words are equivocal. (Or do you disagree?)
