I hope they sang cheery little ditties about slaughtering Christians and Jews, too, perhaps set to the tune of "Mary Had a Little Lamb."
Mohammed strapped on his vest
Little vest
Suicide vest
Mohammed strapped on his vest
To blow up infidels.
He blew them all to smithereens
Smithereens
It was keen
He blew them all to smithereens
And went to meet his virgins.
