INFINITE's Sunggyu roused up some laughs on JTBC's 'Please Take Care of my Refrigerator' on June 29 by directing light jabs at Jung Hyung Don.�

He said, "Not too long ago, I contacted him, but there was no reply. �Jung Hyung Don said to me, 'Oh, you didn't know I changed my number?' �He had to tell me [he'd changed his number], but he had not told me. �It made me think this is why I could not be close to celebrities."

He said toward Jung Hyung Don, who was as amused as everybody else, "I treated you so well, but celebrities' personalities... �What you see of [celebrities'] personalities on TV is not all there is," making everyone chuckle.
