H: I just thought it was a natural nickname progression. "Summer" becomes "Sums", "Sums" becomes "Products".

H: There's no end to it really. "Products" can go to "Quotients" to "Squares" to "Exponents", eventually all the way up to "Divergences", "Dirac Deltas" or even "Laplacians"!   

S: You're such a math geek.
H: What say we take the limit of x as my foot approaches your ass!?
