When I tried to convince the Southerners to abolish slavery and not take on the North, they damn near lynched me.
When I tried to persuade the Athenians not to embark on the Expedition to Syracuse, they thought I was a Spartan agent. Had Aspasia not hidden me in a very large amphora... (She agreed with me, by the way. I'm still in love with her!)
When I tried to explain the germ theory to Elizabeth I, she thought I was a witch and damn near locked me in The Tower.
All was not lost, however.
I did manage to persuade Isabella to sell her jewels and send Columbus to India (an ounce of inaccuracy is worth a pound of explanation).
And I did help Cleopatra get over Caesar. (Ooooo was she good to me.....!)
