Harley Quinn (2016) #49 (VAR ED)

Harley's straight-up clowning around on her latest mission, and she's faced with a real laugher of a puzzle: How does she kill and collect the bounty on Lord Death Man, an immortal murder machine who seemingly can't be killed? Nevertheless, she will persist with a host of attempted assassinations, all doomed to fail. Time is running out, and Harley's running out of material, too!
