Which two companies would be unstoppable the next few years if they merged? Let me start:

$MCD (+0.17%) with their brand and number of restaurants, but with the quality of $SHAK (+3.09%) burgers.

or

$COIN (+2.46%) and $CHWY (-3.48%) - the two already have the same logo anyway - plus Tier products are easy to pay for with the crypto wallet. Simply Meta.
