Joi & Chee Keong (in full Korean Wedding outfit), with Gary, Adeline and myself. 
Coincidentally, Joi's hubby is ALSO called Chee Keong..So before the wedding, I had promised myself not to respond to the name the entire night... Not very successful, haha. Almost everytime someone called out his name, I turn around as well.

Gary (who knows only Joi and me, and not the groom) got confused also..
Gary: Hi, I'm here for the wedding.
Reception: Hmm, can't find your name in the list. OK, are you with the bride or groom?
Gary: ...
Reception: Are you with Chee Keong?
Gary: Yes! Yes! I'm with Chee Keong.
Reception: OK, so let's sit you at the groom's tables
Gary: (slowly realizes..) Wait, Wait! nonono! i'm with the bride! (slaps head mentally)...
