Dancing with PCR machines

I am definitely the target market for this ad (lyrics here). I haven't laughed so hard in ages. I particularly love these lines:

Denaturing, annealing, and extending.
Well it’s amazing what heating and cooling and heating will do

And the chorus:

PCR, when you need to detect mutations.
PCR, when you need to recombine.
PCR, when you need to find out who the daddy is.
PCR, when you need to solve a crime
