I think I figured out Justin Timberlake’s secret message in “Suit & Tie”: he’s a stripper.
Think about it: he only ever mentions a suit and tie. Nothing about a shirt, underwear or socks.
Clearly, this is his subtle way of letting the world know that he’s fallen on hard times and has resorted to selling his body to the masses.
That, or he saw “Magic Mike” and was inspired to do the same.
