Pennies from Heaven is also a musical comedy from 1936 starring Bing Crosby which ties in with the later allusion to Singin' in the Rain.

I don’t think any streetwalkers are wearing thousand dollar stilettos. Pusha may well be wearing these:

"Astaghfirullah I'm not a prophet but Fahrenheit 1/15 is b..." (Lupe Fiasco – Dear Fall) | accepted

Astaghfirullah — is an Arabic phrase meaning “I ask Allah forgiveness.” A Muslim says this phrase many times, even when he is talking to another person. When a Muslim abstains from doing wrong, or even when he wants to prove that he is innocent of an incident he uses this expression.

In this case Lupe is making clear that he is not saying something blasphemous (i.e. he is NOT claiming to be a prophet).

Sorry wrong picture:

"Now they hide their head like an ostrich" (Pusha T – Money on My Mind (Freestyle)) | accepted

In popular mythology, the ostrich is famous for hiding its head in the sand at the first sign of danger. A common counter-argument is that a species that displayed this behavior would not likely survive very long. In reality they deliberately swallow sand and pebbles to help grind up their food.
