Both broke their bondage with their pitchman, Mr. Coffin.

Both owned land in North Carolina and forty slaves.

Both were nostalgic for Siam: childhood of preserving 
duck eggs, watching tiger and elephant fights with the King, 
Mother Nok who loved them equally.

The physicians were surprised to find both were "personable."

Both did not appreciate the outhouse joke.
"Are all Orientals joined?" "Allow me to stick this very sharp pin 
in Eng's neck to see if both of you feel the pain." "Is it true that 
you turn babies into cabbages?" "We are nice, civilized people. 
We offer you bananas."

Both were sick of fascination.

Both woke up, played checkers, sired children, owned whips 
for their slaves, shot game, ate pie. Both wore French black silk, smoked 
cigars, flirted. Both believed in the tenets of individualism. 
Both listed these activities to the jury and cried, "See, we are American!"

Both were released with a $500 fine for assaulting another head hunter.

Both were very self-aware.

Both insisted on an iron casket so that grave robbers would not 
dig up their bodies and sell them to the highest bidder.

"My lips are turning blue, Eng" / Eng did not answer.

"They want our bodies, Eng." / Eng did not answer.

"Eng, Eng! My lips are turning blue." / Eng turned to his body and did not answer.
