The gang at our favourite viral content site are at it again. BuzzFeed have always provided us with hours upon hours of diversionary delights, and this time is no different.
In the past, they have been known to put a group of their finest employees, The Try Guys, through a number of weird and wonderful tasks for our viewing pleasure. This time around the Try Guys are inspired by Fifty Shades of Grey to try out bondage.
