The Interview

An Irishman went for an interview with McDonegal's Advertisting Specialties.
The interviewer told him that all applicants had to complete drawing a test
And took a piece of paper and drew six vertical lines in pairs of
two on the paper and placed it in front of the Irishman. 

"Could you please show me a clever way to make this into nine?" 

After thinking for a while the Irishman took the pencil and drew a 
canopy of leaves on top of each of the three pairs of lines,
and handed the paper back  to the interviewer. 

The interviewer looked at the drawings and said: "But that is not nine!" 

"Oh yes it is", said the Irishman with a broad Irish accent,
"Tree +  Tree + Tree makes nine!" 

The interviewer handed the paper back to the Irishman
and asked him to make it 99. 

After thinking for a longer while the Irishman scribbled up
and down the trunks and then smudged the ink and
handed the paper back to the interviewer. 

The interviewer looked at the drawings
and said: "But that is not ninety nine!" 

"Begorrah! Oy yes it is!", said the Irishman,
"Dirty tree + dirty tree + dirty tree make ninety nine." 

The interviewer was now a bit cheesed off
so he decided to do the Irishman in once and for all,
therefore, he handed the paper back to the Irishman 
and  asked him to make it 100. 

After thinking for a considerably longer time the Irishman
suddenly grabbed the pencil and drew a little blop
on the bottom right hand side of each three and handed
the paper back to the interviewer. 

The interviewer looked at the drawings and said: "But that is not 100!" 
"Oh, Danny Boy, yes it most certainly is", said the Irishman with a much broader 
Irish accent,
"Dirty tree and a turd + dirty tree and turd + dirty tree and a turd make 100…"
