 If you liked
Gintama

 ...then you might like
Isekai Ojisan
|
If you like the humors and comedy part of Gintama, then you might also like Iseaki Ojisan.
Although, the world is quite different just because Gintama is not an isekai genre, but if you prefer parody/comedy, then you might think of it as their strong similarities.
-Gintama has trio MC's (Gintoki, Shinpachi, Kagura)
-Isekai Ojisan has also (Ojisan, Takafumi and his friend Sumika)
-Both used insane amounts of reference to other anime, which is parody
-Comedy part is also insanely funny.
