Can a character be tricked into being touch attacked, failing a saving throw, or lowering spell resistance against a spell?
Say for example, Elsa the sorcerer bluffs Bruce the barbarian into letting her cast Bulls Strength on him, but instead she casts Frigid Touch.
Does the touch attack automatically hit because Bruce was staying still to allow Bull's Strength?
Does Bruce forfeit his saving throw or does his body instinctively know something is wrong, giving him a saving throw anyway?
If Bruce had Spell Resistance that he had lowered in expectation of Bull's Strength, does it apply against Frigid Touch because it was not the spell he was expecting?
if you lower spell resistance it's lowered till your next turn, nothing can turn it back on sooner than that.

I'd say the touch attack automatically hits. Someone pointed out in another thread recently that forgoing a save lets you accept the effects of a harmless spell, so I'd say you instinctually resist harmful effects and get the save, if any. Lots of harmful touch spells don't have saves, though.
