Wife: New Shimmer is a floor wax!
Husband: No, new Shimmer is a dessert topping!
Wife: It's a floor wax!
Husband: It's a dessert topping!
Wife: It's a floor wax, I'm telling you!
Husband: It's a dessert topping, you cow!
Spokesman: Hey, hey, hey, calm down, you two. New Shimmer is both a floor wax and a dessert topping! Here, I'll spray some on your mop....and some on your butterscotch
pudding.

Husband: Mmmmm, tastes terrific!
Wife: And just look at that shine! But will it last?
OK - you're both right. The full name of the car is Pontiac Banshee XP-798. It was built but not shown in 1966. Pontiac used the name Banshee XP-833 on the simpler 2-seat sports car they showed in 1964, which shared a similar front end design, but a solid rear axle out back (the XP-798 had an IRS). There was another Banshee (Banshee III) done up in the 1970's that was similar in appearance to the rotary Corvettes form that era. The last Pontiac Banshee foreshadowed the last production Firebird.
