Why is the chapter called “The Sheik”?

This first chapter is called "The Sheik" in reference to Rudolph Valentino. He was a movie star in the early 20th century, a real ladies' man. This is how Vladek (Art's father) describes himself. Indeed, in this first chapter we see Vladek in 2 relationships, and he seems to think much of his appeal came from his self-described good looks. There's one particular panel, where Vladek is riding an exercise bike, but there's a movie poster from The Sheik in the background. There's a noticeable contrast between Vladek's reality and his remembrance of the past.
