EXO appeared on SBS radio program 'Cultwo Show' on April 13 and talked about celebrating (or not really celebrating) one another's birthdays and the y choreography for "Call Me Baby."

Sehun said, "Yesterday was my birthday.  I received a lot of happy birthdays.  I was happy. There was a fan signing event yesterday.  I had a fun time with fans.  I gave out presents to the fans who came to the music show starting from early in the morning."

Chanyeol added, "At first, the members would take care of one another's birthdays well, but seeing as how there are ten birthdays in a year, we've come to naturally stop doing things now.  Now everybody buys his own presents well, so we call it even."

In relation to the choreography, the boys stated, "This choreography is the iest one we've done so far.  We even send hand kisses flying.  We hit our chests and our pelvises. The stage version is different for each broadcast and the MV version is different and our appearances change, too.  The version is different depending on the number of members, so there are times we get confused about the choreography."

Well, it doesn't really show as the boys confidently dominate the stage regardless of which choreography they're doing!  Happy belated birthday to Sehun!
