Mick and Paddy were walking home from the pub.
Mick says to Paddy, 'I cant be bothered to walk all that way.'
"I know,' says Paddy, 'but we've no cab money the last bus has gone.'
'We could steal a bus from the depot,' Mick suggests.
They arrive at the bus depot and Mick tells Paddy to go in and get a bus while he keeps a look-out. After shuffling around for ages, Mick shouts, 'Paddy, what are you doing? Have you not found one yet? '
Paddy shouts back, 'I cant find a No. 91 '
'Oh Jeysus , ye thick sod, take the No. 14 and we'll walk from the roundabout ?
