Miniscule Stack on the Bubble - Question

[CMP]

4 people left in a $5.50 SNG on pokerroom.com. Stacks are roughly T6K, T4K, and T5K, with me at T280.

I'm on the T200 SB and have T80 left after posting.

UTG (T5K) goes all-in (except for T90) and chip leader (T6K) calls.

UTG has been playing crazy all day, very aggro pre-flop, often shows down nothing.

In any case, is this an easy fold, easy call, or what?
