To borrow money on the credit of the United States;

The Congress shall have power to lay and collect taxes, duties, imposts, and excises, to pay the debts and provide for

Article IV, Section 1: Full faith and credit shall be given in each state to the public acts, records, and judicial proceedings of every other state. And the Congress may by general laws prescribe the manner in which such acts, records, and proceedings shall be proved, and the effect thereof.

To tell the truth, I can't find an "interstate-commerce clause" of the US Constitution. I'm going to guess it's the full faith and credit clause, but I could be wrong.

Spring Break!: "I hate it when a student e-mails me announcing that I have to give him a make-up exam, especially when it clearly says on the syllabus that there are no make-up exams. (Sorry for venting, but I can't vent at the students. They are so sensitive.)"
