I'm in Heaven

For reasons that we don’t need to go into right now, Paddy (for it was he)  was on his way to Heaven.
Upon his arrival at the Pearly Gates, a Concerned Saint Peter was waiting for him.

“I'm sorry Paddy”, said Saint Peter, “but Heaven is suffering from an  Overload of Goodly Souls at the moment and we have been forced to put  an entrance exam in place for new arrivals to ease the Burden of Heavenly Arrivals.”
“That's all right”, said Paddy, “what does the entrance exam consist of?”
“Just three questions”, was the reply.

“Which are?” asked Paddy, when no further information was immediately forthcoming.

“The First”, said Saint Peter, “is: Which two days of the week start with the letter 'T?”

“The Second: How many seconds are there in a year?”
“The Third: What was the name of the swagman in Waltzing Matilda?”
“Now,”' said St Peter, “go away and think about those questions and when I call upon you, I shall expect you to have the right answers for me.”
So Paddy went away and gave Those Three Questions some Considerable Thought (and we expect you are doing the same).
The following morning, (where did he spend the night?? –Ed) Saint Peter called upon Paddy and asked if he  had considered the questions, to which Paddy replied

”Indeed and I have sir”.
“Well then”, said Saint Peter, 'which two days of the week start with the letter T?”
And Paddy said ”'Today and Tomorrow.'
St. Peter pondered this unusual answer for some time and finally decided that indeed it could be applied to his question.
“Well then Paddy, could I have your answer to the second of the three questions?”

And St Peter went on

“How many seconds in a year?'

And Paddy responded

“Twelve!”

“Only 12?” exclaimed St Peter, “how did you arrive at that figure Paddy?”
“'Easy”, was the reply, “there's the second of January, the second of  February right through to the second of December, giving a total of twelve seconds.”
And Saint Peter looked at Paddy for a Long Moment and said

“'I need some time to consider your answer before I can give you a decision.”

And away he went in Some Confusion.

He finally returned and said

“I'll allow that answer to stand Paddy, but you need to get the third and final question absolutely right to be allowed into Heaven.”
And he said

“Now Paddy, can you tell me what was the name of the swagman in  Waltzing Matilda?”
And Paddy replied

“Of the three questions, I found this the easiest to answer!”

“Really!” exclaimed St Peter, slightly alarmed, “and what is the answer then, Paddy”'
“'It's Andy.”
“Andy??”, Peter’s voice dropping an octave.
“Yes, Andy” said Paddy confidently.
And Saint P was totally floored and he paced this way and that for a while pondering What To Do.

Finally, he turned around and said

“Paddy, how in God's Name did you arrive at THAT answer?”
“'Easy,” came the reply  ”Andy sat, Andy watched, Andy waited till his billy boiled”.
 ………..and Paddy entered Heaven...
