"Mummy?!" Decried the old lady. "I'll have you whippersnappers know, that I ain't your mummy. Well, not since I had my gash stitched up in a backstreet transgender reassignment clinic in Bangkok. Dinger, Stan, this may come as a surprise to you. But I'm actually your father. Hello sons."
"Trowel may have a point", said the transgendered octogenarian. "Do your old father a favour and slot the cunt, will yer?"
"Aye" said Dinger. "But why have you been away so long, pappa?"
"Regretfully sons, events conspired against me. I remember cooking your other dad's tea one wet November night. I could take no more of his drunken brutality, so I waited until his drunken rage had subsided, and he was fast asleep with his fingers down his y-fronts. I just knew I had to escape. I packed my bags and went to Bingo at Vickers on the Scotswood Road. I knew then that my destiny was about to change. I caught the number 11 bus to Whitley Bay, and then I went on to North Shields. From there I stowed away on a pilchard trawler, but we got lost and ended up in Bombay. After spending a few months under the guidance of the Hindu Guru, Swami Swampi, I knew that my true calling had arrived. I walked for three years until I reached Bangkok, and just knew I had to have a c0ck. Then, one day, whilst I was pondering the implausibility of the continued expansion of the universe, I saw both you boys on the evening news. It brought a tear of pride to my eye. I could tell, from your postures, that it was my fine sons who were on the balcony. Then I made a pact; I would come back to claim my rightful place as head of the family. In the great British tradition of improvisation, I procured a rowing boat off a local eel fisherman and began to row to my boys, to my destiny. Sons, I am back"
