Blue secretly likes puns. He just acts like he doesn't like them so his brother would stop making bad ones and actually add more effort into the jokes themselves as to try and make Blue like them.
His favorite type of joke are science ones. (Blue is also secretly a huge science nerd, because yes)He once laughed at a science joke Underswap!Undyne said, she then went straight to questioning his science knowledge.
Like all Sans', Blue has quite high IQ, and a love for science.
. . . Though I say ' all Sans' ' . . . Ink does have his moments when he can be pretty dumb-

FanfictionThese are just a few headcanon's of mine. Enjoy reading this weird stuff. Art doesn't belong to me, it belongs to the original artist(s). Characters do not belong to me (Unless said so). Yeehaw.
