"Chemistry song 04" joke

Silent Labs

Silent labs, difficult labs
All with math, all with graphs
Observations of colors and smells
Calculations and graph curves like bells
Memories of tests that have past
Oh, how long will chemistry last?

Silent labs, difficult labs
All with math, all with graphs
Lots of equations that need balancing
Gas pressure problems that make my head ring
Santa Chlorine's on his way
Oh, Please Santa bring me an' A'.
