Why does Allen laugh when he meets a white deer?

In a variety show, in the challenge of suppressing laughter, Allen stopped the white deer from laughing and complained that her smile was low. The expression of the white deer was immediately made into an emoticon, and the white dew itself was low. People who have a generous personality and love to laugh are not too bad luck. Hi Pai is a variety show. In this program, Allen and White Deer are in the same scene, because of their low laughter and because they both have funny cells. So Allen can't laugh when he meets a white deer. You can watch the program by yourself.
