Forgetful (3.5e Flaw)
From D&D Wiki
You just can't... re-... rem-... what was that word again?
Effect: You take a -2 penalty to all profession skill checks and a -5 penalty to all knowledge checks. Gather knowledge skill checks are also treated as though they were made with a -5 penalty when sharing gathered information.
Roleplaying Ideas: Remainder! That's the one. You just can't remainder things very well.
