A popular Korean online community is obsessed with the TWICE members playing with a scalp massager with one another. The post is titled, 'Girl group that is addicted to scalp massager,' and it shows several GIFs of the girls playing with the popular massager at fan events. 

Mina likes to surprise members with it... 

And here they are again, at another fan event... 

It seems like Dahyun is used to being ticked. She isn't fazed at all. 

But Jungyeon needs time to get used to it! 

One netizen commented, "So cute! Wonder what the massager feels like?" Another commented, "Dahyun is very calm. Guess she doesn't feel tickled?" One person wrote, "I'd like to be that massager." 

Don't we all? What other funny presents would the TWICE members enjoy?
