Proving the regularity of a certain language I've been fumbling around with this problem for the last hour, and I'm incredibly stumped.

Let $A = \{\; 0^ku0^k \mid k ≥ 1 \text{ and }u ∈ Σ^*\;\}$. Show that $A$ is regular. 

The language obviously satisfies the Pumping Lemma, but that is not conclusive for regularity. How on earth do I prove that this language is regular? I'm aware of all the normal methods (closed-under, etc), but I cannot for the life of me figure out the appropriate condition to continue.
It is a trick question. You can find a simpler form to describe the language.
