You had me at Immoral

Some might say he was insane
for that I might cause them pain
Maybe a little misunderstood perhaps
or having a couple of judgment lapse
I knew he was for me
when for the whole world to see
he tried to make his horse a consul in his Empire
It fueled my desire
He might disrespect the Senate and Roman traditions
but for him I would try different positions
excessive cruelty and immoral sex acts
make my heart react
Incest is bad
But what do I care when you make my heart glad
On your Pontoon Bridge we could stand
and survey all your land
Because Caligula, you had me at Immoral!
