HaHa was disappointed by his own height on 'Infinity Challenge'.

The March 2nd episode featured a�special called 'Competition Against Myself', and the cast members started off by getting their health examined.

When the cast's measurements and vitals were compared to last year, it was revealed that HaHa actually shrank in height. He previously measured in at 172.5cm (5'7.9"), but apparently, the singer is now 171.4cm (5'7.5") tall.

Disappointed, HaHa whined, "How can I shrink?" while the other cast members made fun of him.

It's okay. Byul probably doesn't mind.
