You have embarrassed yourself twice today and now going for the third.<quoted text>Check the meaning of pun a little more carefully, but at least you're trying...(Hint: Telling someone he has his finger in a dyke is a pun; calling someone a dike isn't--now figure out why.)

Note the word 'like' in the sentence. It is also another one of those literally devices called a simile.
Maybe you should stick with your grammar checker.
