Feline Intervention Question

[Xenoris]

The People playing were divided over this question while playing Munchkin last night.
The situation was that feline intervention was played after someone rolled to run away. They had the tuba of charm and some people thought that should be discarded in accordance with Feline Interventions: discard all cards the effect the roll clause.
My counter argument is that the tuba affects "run away" not the roll. If it was something like loaded die or maybe even chicken on your head. Then it should be discarded.
Is this right?

I'm almost certain you are correct. Run Away modifiers do not affect the roll, they affect the result of the roll.

Curse: Chicken On Your Head wouldn't be discarded, though. It also affects the result of the roll.
