I think I have just found what will soon be featured on random nerd pr0n sites all throughout the net. Now there will no longer be random Harley Quinns not captured, no, they shall be adorned with replica Batman cuffs.
They are actually the same size as the average police handcuffs and fold in half for easy transport. Any boys with a mischievous girl should be careful though since they don't mention anything about a safety release and boys in Batman cuffs just look slightly homosexual.
Even though sometimes I wonder if Batman wouldn't have rather used these cuffs on Robin as opposed to Batgirl. These fully functioning cuffs with 2 keys are scheduled to start being sold in January of 2009 and is priced at $136.99.
