Russian Scientist

The mumbling Russian scientist with his collar at his ears
Gave the longest, driest lecture to a congregation of his peers
"It was here we noticed this," and "This was the observation,"
So continued this rigid and rehearsed, rather worn old recitation
"It was proved in '62 by Prof and Doctor both now dead,"
"It was shown before my birth by this institute's great head,"
"There are further works to do, but my health's a consideration
in limiting my contribution to the knowledge of my nation,"
Very publicly he revealed the truth, which comes as no surprise
Nobody knows everything and everybody dies.
