We Irish have enriched the English language with a   slew   of   snazzy   gems. Did you know we're the ones behind   quarks  , electrons  and   vectors  ,   Sudocrem  and   Wellington   boots? No surprise that we invented   begrudgery  , but   croquet  and   Wunderkind   were us too! So if some   yahoo   is   getting on your nerves  , don't box him in the   gob   - hit him with Irishisms   galore  , and you'll soon put the   kibosh   on his   shaninagans  . Y'  dig  ?  Written and illustrated by Colin Murphy and Donal O'Dea, the  craggy  old  blokes  behind the bestselling Feckin' Collection and Stuff Irish People Love.
