pretty much same kind of gags, 3 of them, a really strong girl, the leader always shows his charisma when its needed while being a irresponsible at all times (not so much on bossun), glasses :D, the yorozuya in gintama does anything for money while the sket dan does any request, both do odd jobs. the yorozuya rivalry between shinsengumi (like the police) is just like the rivalry between the sket dan and student council. a character in the shinsengumi that is a bitter rival to the main character just like bossun and tsubaki, a joker of a leader in the shinsengumi and the student council but everybody respects him. and of course, mutual respect between the two rivalries of the yorozzuya and shinsengumi, just like the sket dan and student council
expect toilet jokes (my favourite wooooo) and jokes that won't be restricted by the sket dance's high school theme
sket dance's mangaka used to be the assistant of gintama's mangaka.
