Contagious

Irish joke of the year 2006

A teacher asks her class to use the word "contagious". Roland the teacher's pet, gets up and says, "Last year I got the measles and my mum said it was contagious.""Well done, Roland," says the teacher."
Can anyone else try?" Katie, a sweet little girl with pigtails, says,"My grandma says there's a bug going round, and it's contagious."
"Well done, Katie," says the teacher. "Anyone else?"
Little Irish Sean jumps up and says in a broad Dublin accent, "Our next door neighbour is painting his house with a 2 inch brush, and my dad says it will take the contagious."
