formal::

P(x) = x is a Providence; S(x,y) = x protects y; R = union of the four sets: idiots, drunkards, children, USA

βˆƒx,βˆ€y∈R,P(x)∧S(x,y) \exists x, \forall y \in R, P(x) \land S(x, y)

formal::

E(x) = Event happens to x, F(x) = x is funny

βˆ€E,E(Β¬me)β‡’F(E) \forall E, E(\neg me) \Rightarrow F(E)
