An English professor told his class that they wouldn't be meeting for a few weeks. ""I don't want you to worry,"" said the professor, ""but I'm going to be out for a while. My doctor found some tumorous neoplasm on a CAT scan and wants me to have it removed before it develops into cancer."" The students started muttering, but one of the snarky pre-med students in the back of the classroom raised his hand. ""Professor, that was redundant. Neoplasm and tumors are the same thing. I doubt any doctor would have called it 'tumorous neoplasm.'"" The English professor smirked. ""You're right. I just always wanted to make a [pleonasm](https://en.m.wikipedia.org/wiki/Pleonasm) out of 'neoplasm.'""
