My fellow what?

This is a sketch from British TV show, "DeadRingers".
Dead ringer means someone who bears resemblance to somebody.
As you know, he impersonates Mr.President, but he said like...

"My fellow ostriches!"
"Today has been a great day in the war on terry hatcher!"
"Alqua pow wow brought death and destructification to Iraq on a massive snail."
"The threats opposed by his detergents is vanished."

hahaha!
