Bad pint
Heard in Limerick
The one bad pint many people accidentally drink along with the 15 good ones also consumed that causes the person to be sick as a plane to lourdes the next day.
I can't understand how I'm so sick today. I must have got one bad pint.
I cannot fathom why I feel so exceedingly unwell this morning; I must have ingested a single unfortunate pint amongst the fifteen pristine ones.
