A Bahraini man is claiming to have broken the world record for the longest non-stop talk, reports say.
Mr Nasser survived on warm water, coffee and custard
Management trainer Jameel al-Nasser, 56, started the 66-hour marathon on Wednesday at 1930 local time and finished 1330 on Saturday.
He is waiting for official confirmation of a place in the Guinness Book of World Records.
He spoke in Arabic about neuro-linguistic programming, taking breaks every eight hours to pray and eat.
Mr Nasser told the paper his success could be attributed to his subject matter.
"The subject was very close to my heart and I was able to speak volumes on that," he said.
"My whole family was there to support me."
But it was not all plain sailing.
"On the first day I was strong [but] on the second day I became weak," he admitted.
"I was not able to eat anything and I was having only warm water."
However, by the third day, he said he had managed to perk up and felt that Saturday was his best day - despite having consumed only warm water, two cups of coffee and custard for the duration of his talk.
"I was so enthusiastic to win I just could not eat. But, anyway, I am glad that I have succeeded," he said.
Mr Nasser must now send two witness statements and a video of his talkathon to the Guinness Book of World Records in the UK, to win his place, the newspaper reported.
The current record is held by Zimbabwean Errol Muzawazi, who spoke on Polish democracy for 62 hours.
