The scourge of plagiarism - As I have noted before–plagiarism irks me (more accurately, I despise it). Not only are the students who engage in the activity not learning what they are supposed to be doing, they are both stealing and lying. And, to top it all off, I have to spend time figuring out the source so that I confirm from whence they have stolen in their attempt to lie to me. (Hat tip: Poliblog)
