A: Hey man are you okay? What'd you do all day, didn't hear from you at all.

B: Yeah, I'm fine, just took a ride on the A train. Cleaned my room top to bottom, alphabetized my DVD's, and got all of my laundry done. AND finished that paper I put off for 2 weeks.

Get the A train mug.
A New York City subway train (the Eighth Avenue Express) mentioned in Duke Ellington's signature song "Take the A Train" and famously performed by Ella Fitzgerald. The A Train passes through Harlem, stopping at 145th Street ("Sugar Hill"), a center of African American culture during the "Harlem Renaissance" between the world wars.
You must take the A Train / To go to Sugar Hill way up in Harlem / If you miss the A Train / You'll find you've missed the quickest way to Harlem ...

"Take the A Train"
