Such a capacitor would store 0.5 * (.33e-6 F) * (275 V)^2 = 1.25 Joules. Suffice to say it would probably hurt, as it's about 2% of the energy in the sometimes deadly microwave oven capacitors.

As someone who accidentally touched one, I can say it hurts like hell but doesn't do any lasting damage.

Hurting without causing lasting damage? Sounds like the kind of thing the CIA would be interested in.
