You’ve Probably Never Heard A Sink Make This Sound Before

This sound pisses me off! We're not plumbers or anything, so we have no idea what's causing this sink to make such a noise. But the owner should probably get on Angie's List and get someone to come take a look at it stat.

Is there air in the pipes?  Is this a result of fracking that will eventually lead to the water lighting on fire?  Who knows!  The sad thing is I can't fix this problem, I'd have to fly my dad from Seattle to fix it for me.
