I don't know if this counts as lawyering, but it's definitely the dumbest use of rules I've encountered post-Junior-High. Apologies in advance if the subject of this is an ENWorld member.
I once read a post on r.g.f.dnd by a DM who used initiative to handle... NEGOTIATIONS.
Basically, the players (and him, too I guess) were either sick of or feared the possibility that someone they were talking to might conceivably "get the drop on them" while they talking to or interrogating them. That is, suddenly whip out a weapon and maybe get a higher init roll, leaving them flat-footed until they got a chance to act.
So, basically, anytime this party dealt with almost anyone, they would switch to "initiative mode"; everyone rolled initiative and then each PC/NPC spoke on their initiative count. This way, nobody was ever flat-footed in the event that the person they were talking to decided to attack.
I tried to explain why this was so dang stupid, but they guy pretty much ignored me.
I mean, not only is this SERIOUS metagaming ("We go into initiative mode so that we can't get sneak-attacked," said the cleric), but it essentially takes the control of time (i.e., the decision when the game needs to switch to combat rounds) out of the hands of the DM.
Beyond dumb.
