In this episode he encourages the ice maiden to be a neet.
Indeed (but she'll be back to uncle later).
Also did you notice that some of his words for Mabel (the Ice Maiden) seem like it was inspired from Sonic 2 JP cover artwork (upper right)?
"Don't just sit there and waste your precious time.
When you want to do something, do it right away.
Do it when you can.
It's the only way to live a life without regrets."
