Stupid Player Tricks

This is just brainstorming, don' know that I'd ever inflict this on players. Trying to come up with ways that in-game effects might be "felt" by players as per here. So, as long as players are under the effect they must:

• sit with their chair turned away from the table, their back to players/DM
• turn their character sheet upside down and interact with it in that way
• any notes or writing they do must be in something ridiculously hard to read like yellow crayon, or highlighter
• no writing allowed, they must remember anything they would normally make note of
• no talking allowed, either communication by note, or by gestures
• blindfold
• all dice must be rolled with off hand
• if using minis, must substitute their character's with a troll (unless troll use considered normal)
• sit in another room calling out their player actions
• write down plans of action for combat/npc interaction etc., give them to DM and then they must abide by those exact actions when the situations arise
• always last to act in order of battle
• finger puppets
  

Okay, some of those would definitely be un-fun. But I kinda like the "roll dice with offhand" rule. It doesn't seem too onerous and if I were the player it would bug me to have to roll to hit like that. I would want to do whatever to get that effect off of me.

Any other ideas?
