Yezt becomes extremely agitated by the uselessness of his weapon, and his voice trembles as he runs back toward the bar. "MY KINGDOM FOR A DAGGER!" He screams at the barkeep and remaining patrons, simultaneously scouring the bar top for a large bottle of wine or something similar.
Actions: 5-foot step to the side (he withdrew from the zombie's reach last round) and then move toward the bar. If no one is able to provide him with a dagger, grabs a large bottle (should there be one in the area) and use a standard action to break it for use as an improvised dagger. (I'll gladly take the -4 to attack if I can just do some freaking damage...)
