This is the $20 Couch Coaster, a piece of molded silicone with weighted arms that hang over the sides of an armrest to provide a safe place to rest a drink. It also has a cutout in the back to accommodate coffee mug handles. Admittedly, not the worst product I've ever seen, but who needs a coaster when you've got a drinking helmet? I own THIS ONE. My friends really love it because it makes me super easy to spot and avoid whenever we go out.
Keep going for a couple more shots including what appears to be an older couple from a boner pill commercial, as well as what a sad Couch Coaster looks like with no drink to hug.
Thanks to hairless, who just uses a three-foot krazy straw that reaches to the coffee table.
