world then?" 2nd Irishman - "I know - Tinkin' - ya tink of a thought, it's
there. Fastest ting in the world - tinkin'" 3rd Irishman - "No, no, no Paddy.
you're talkin' shite. Blinkin - dat's the fastest ting in the world. You
Blink - it's over already - done. The fastest ting in the world." The first
Irishman comes in again: "You're both wrong. It's electricity. Ya turn da

point a 4th Irishman comes into the pub. "Hey", he says, "I've been hearing
you tree goin on about da fastest ting in the world and you're ALL wrong."
1st Irishman says "Well come on then mate, tell us what the fastest ting in
the world is." 4th Irishman replies "Curry. It's easily the quickest ting in
da world." The other three say "EH?!" 4th Irishman: "Oh yeah - I had a curry
the other day - I woke up in the middle of the night and before I could
think, blink, or turn the light on I'd shat meself!"
