Samurai Jack - Only one person celebrates that episode. And it's Aku

Later at the party

Mojo was told there would be deviled eggs and tea…Mojojo is DISAPPOINTED!

I have empire to run and 2 teenagers to hunt down along with their robot. Please make this celebration brief.

This celebration of human weakness is meaningless…were you not a creature of old evil I would have burned your from the inside the moment you asked me to celebrate a pointless human event

Father, I hope you understand this counts as your birthday and Father's day gift.

Please keep at least 20 feet away from me, you don't wanna violate the restraining order do you?

meanwhile in the background Bill Cipher is simply rocking it along with Aku.
