During a special corner called 'Stretch Rubber King,' the GOT7 members each showed off the flexibility. JB in particular recorded 42cm (~16.5 in), breaking the 40cm (~15.7 in) record set by Red Velvet's Irene. 

The MC's marveled, "He beat a girl group," to which JB replied confidently, "Even if Irene comes on again, I can win." 

Did I just hear a battle cry? Irene, you better get stretching if you want to keep your record on 'Weekly Idol'!
