This is a confusing meme, because in the skit the parrot is dead when bought. It had been nailed to its perch to make it look alive and the seller told a series of funny lies. The bulk of the joke is how unreliable the pet shop clerk is.

In contrast, Twitter was obviously in bad shape (that's why Musk was making a buy offer in the first place), the board was not interested in selling until he made a wildly over-value offer, and Musk immediately tried to back out of the sale and had to be forced to comply with the deal he'd made.
