Super Junior's leader Leeteuk and entertainer Boom made fans howl with laughter over their imitations.

On January 15th, Leeteuk uploaded a photo onto his Twitter and wrote, "Former wrestling legend 'Hulk Hoteuk' and Pop industry's 'Lady Boom Boom'."

In the photo, Leeteuk made a hilarious attempt to copy wrestler Hulk Hogan's signature biceps and yellow outfit. Meanwhile, Boom transformed into global superstar Lady Gaga with a long, blonde wig and awkward stage outfit.

So, why did these two dress up this way? It turns out they were the MCs for the upcoming '4th Idol Star Athletic & Swimming Championships', which is scheduled to air on January 24th. Leeteuk and Boom came out in these costumes to kick off the event in lively style.

Netizens commented, "BoomTeuk Academy~, wish it lasted forever", "Can't wait for the show!", and "I'm laughing already, I bet the show will be even more hilarious!"
