Favorite Gintama Ep?

Gintama is now on it's 212th episode and is still yet continuing.
I was kind of thinking about rewatching some, so was curious if anyone had any memorable eps.
I think my favorite ep was: "Once Upon a Time in China Girl Gintama" episode 50 (season 2).
It was the episode about ideas to "change up" Gintama to make it more popular.

Spoiler:

Out of all the ideas I think I liked Kagura's idea the best (which is the title of the ep).

yea, I'm not sure if this is my fav but i liked the episode where they were stuck in an elevator. So they ended up playing 'magical banana'.

Another one is when all the guys suggest new theme for gintama'. And they get random ideas, for example 'NaruBleaBall'

i like the hot pot episode, thats ep 25.

Nabeleon! Nabe Shogun!

i like the game console ep think its 98 and 99
