Bill Gates has transitioned into a primary role as a philanthropist, dedicating a substantial portion of his net worth (typically $60-70 billion) to the Bill & Melinda Gates Foundation, which finances AIDS research (among many other endeavours)

Since the B&MGF has nearly $40 billion in endowments, and Steve Jobs had a net worth of $8.3 billion at the time of his death, this claim is actually probable

In Elvis' final years, his disgusting eating habits (e.g. “Fool’s Gold Loaf”) caught up with him, and his obesity became a defining aspect of his later image

Frank is likely implying Cleopatra has betrayed her race.

You could also view Samson’s “full head of hair” as an implication that the narrator feels inferior compared to him, considering his hair granted him superhuman strength. This would also fit in with the impotence of the unemployed narrator towards the end of the song.

This also alludes to the fact that Cleopatra made alliances with rival rulers, often with the use of sexual favors. Samson, having his hair full could mean that he has certain power that she is after and, in turn, betraying her blackness and the king, for his power.
