The check is in the mail jack burton shirt

A classic reference!

"The Check is in the Mail" is a humorous phrase that originated from the 1987 film "The Princess Bride" starring Cary Elwes and Robin Wright. The phrase is spoken by the character Vizzini, played by Wallace Shawn, as a humorous way to avoid paying a debt.

And, of course, "Jack Burton" is the protagonist of the 1986 film "Big Trouble in Little China", played by Kurt Russell. The character is known for his rugged individualism, wisecracks, and iconic leather jacket.

So, putting the two together, "The Check is in the Mail Jack Burton Shirt" would be a humorous mashup of the two references, implying that Jack Burton is trying to avoid paying a debt by claiming the check is in the mail!
