Irish joke

'have you heard the one about the irishman?'
Sick and tired of irish jokes
He said farewell to all his folks (bye bye)
Left his home to have some fun
Packed his clothes and a gatling gun
Secretly, with ill intent
Into the house of parliament
Where politicians sit and croak (hear hear)
Inventing all those racist jokes
He pulls the gun out from his coat
And loudly shouts out 'here's my vote!'
'have you heard the one about the irishman?'
'...he had the last laugh.'
