I'm not so sure Mort has a problem with being made fun of over a message board for something like this (I don't know the details of the matter and quite frankly don't care, as they're irrelevant to the main reason why the incessant jokes irritate me). It's more so the fact that the same fucking unimaginative joke with a slight alteration is posted at such a frequent rate that he doesn't even have to be involved in the topic anymore for it to show up. Some people can make poke fun at him in a humorous manner, but it's mostly just users striving for cheap laughs that turns a page into a cesspool of annoying retardation.
The whole matter is almost identical to the "racism" on the board, really.
