@Setanta,
Back in the day there used to be a character called Bingo who traveled on all the buses in Dublin, actually there was a few characters, I remember Bingo and Bang Bang but there was others. We all knew them, if you were sitting on a bus and you heard somebody shout "Check" you knew you were on Bingo's bus. Bang Bang was hilarious, if you were shot, with a finger, getting on the bus, well obviously you were on the Bang Bang bus.
Mother: "What bus did you get into town today son?"
Me; "I got the Bingo bus Ma."
