Gintama - Season 4 Episode 50 Santa Claus Red Is Blood Red

It's Christmas in Edo and Kagura writes her father a letter. She is sad that Santa Claus never visited her. Moved, her father Umi Bozu dresses himself up as Santa and hides watching Kagura, Otae, Shinpachi and Hasegawa celebrate Christmas. When he finally jumps out of the bushes to surprise her there is another Santa, a dressed up Gintoki. Both of them think that their counterpart is real. They start punching each other when another three Santas show up (Sachan, Kondo and Kyubei). Kagura decides on a contest to see who's the real Santa.
