Luigi is such a schmucky character that his name has become synonymous with the perpetual second fiddle, the subservient sibling, the loser brother nobody wants to be like and everybody picks on- even Toad.
So, according to this Owl Turd Comics strip, Luigi is like Thursday and while I agree to some degree I tend to think of him more like Sunday- pretty chill but also pretty depressing, considering Monday is right around the corner.
Sunday, like Luigi, can be awesome on occasion but overall it can't compare to its far more fun siblings Friday and Saturday, plus hanging out with Luigi is like going to church- booooooring!
