Gintama, D-Frag! Recommendations
Theme's different, but both share a boke and tsukkomi shtick, and characters have additional background provided for "serious" depth.
D-Frag! has the same kind of gag comedy and the ramdom feeling of the episodes of Gintama. D-frag! is less bizarre than Gintama. Both have the tsukkomi and boke characters in the main cast.
