I got my new credit card in the mail today, and needed to destroy the old one. I asked Alex if he had a pair of scissors for destruction purposes. He said he had something better: the magic bullet. However, the credit card was tougher than we thought, and refused to blend nicely. Alex then attempted the garbage disposal, which also did not destroy it. Then I found a pair of scissors on the counter.
Lesson: Credit cards do not make good milkshakes.
