Neat, but also hilarious! Searching for "mug" gives results where the first item listed (ABC-00008297) is a mug model with a hole not only in the top to pour in your drink, but also in the side and bottom (just in case you wanted more access to your liquid).

Not the first one... but the "pair of interconnected mugs" that is described as "emphasizes connectivity and collaboration, suitable for serving beverages in a shared or communal setting" is pretty amazing too. I never knew I was missing out on communal mug holding.

Yeah, this looks like something you might hang from a wire or string with a slot for a dowel. A+ for effort though, lol!
