Just a week after putting his feud with Justin Bieber to rest on "The Ellen DeGeneres Show", Seth Rogen poked fun at the singer. In an interview on "The Howard Stern Show" on Tuesday, November 17, the Canadian actor/director compared his penis size to Justin's.

When host Howard Stern asked Seth whether or not he saw Justin's penis picture online, he said he did. Of how Justin's private part looked like, the 33-year-old actor said, "It's not bad, [but] it made me feel good about my [penis] because everyone's like, 'This guy has a huge [penis],' and I saw his and I was like, 'To his scale, it's like an O.K. size. It was a pretty good size.' "

"His frame is so small, if you took off my [penis] and put it on his body, pound for pound, I don't know, it might be bigger," Seth jokingly explained. The "Neighbors" actor went on saying, "I tell you my balls are saggier." Seth insisted that his penis is bigger than Justin's but it looked just normal size because it's on his big body.

During the interview, Seth also revealed that he felt bad for what he did to Justin in the past. "I was hard on Justin Bieber... and he was ultimately incredibly cool about it," said Seth. "He never attacked me back, and he literally has an army of crazy little motherf**ker that he could have sicked on me." He admitted that he was a d**khead for confronting teenage Justin.
