The announcement of Happy Meals for grownups appeared to be both a clever marketing ploy 

For McDonald's and a funny tale that would make everybody else laugh. 

Four-eyed toys mostly in the fashion of something like the iconic McDonald's figures.

 Now they are packaged for adults in a cactus plant flea market.

 It looks destined for worldwide popularity.   The hyper-popular offer, it appears.

 That was having a negative effect catastrophically on the genuine McDonald's personnel.

Who allege it has caused chaos and unhappiness as employees battle to complete an avalanche of order.  

 One staffer posted on TikTok, "bro please don't order those adult McDonald's happy meals bro I'm pleading."
