Comedy from Tragedy
There was a case a while back, reported in the Register but I forget which journal, where a researcher was fed up with being spammed for contributions. He wrote a mock paper that had fancy technical sentences and graphs, etc. It was funny and silly (El Reg gave the link) and they published it.
When a large number of people started laughing at them, they talked about suing the researcher for damaging their 'reputation'. He pointed out that there was no contract between them and they had asked him to provide a paper. He could also have said that he was always under the impression that they were a comedy journal.
