I found another version here.

UNCLE JIM
Attributed to Seamus Browne WF

Oh, Jemima, just look at your Uncle Jim,
All there in the duck pond a-learnin' to swim
He first tries the backstroke, he then tries the side
But he's now underwater, aswim 'gainst the tide.
Tooraloo, tooralee, O how would you, how would you like to be me?
Oh, the oul' barn door was the table we had
And the table we had was the oul' barn door
And the oul' barn door was the table we had
Yes the table we had was the oul' barn door, Tooraloo, Tooralee...
When I was out walking with my brother Jim
Somebody threw a tomato at him.
Now tomatoes are soft when they're inside a skin
But this big tomato was inside a tin.
Tooraloo, tooralee...
