I would like to nominate [[User:I B Wright]]'s current endeavour on [[Pentagrid converter]] for [[WP:LAME]]. He keeps re-inserting a piece of text that is completely nonsensical. He claims that it's a "literary device" and insists that "all the vacuum-tube-savvy editors are happy with it". Four different people have already removed it (myself included) and he keeps reinserting it.
I think it needs to be lame on both sides of the argument to qualify for WP:LAME. Thanks for the laugh, though! It looks like he's reverted it 4 times - I suggest you report him under 3RR, that should stop him.
