Cleveland show - similarities

I just watched most of the first season of the Cleveland show and, although it has it's moments, I realized it really is just a collage from other shows...

Cleveland Jr: Barry (American Dad)
Cleveland: Peter (Family Guy)
Dana: Rochelle (Everybody Hates Chris)
Roberta: Hayley (American Dad)
Rallo: Sewie (Family Guy)

I don't own any of this shows, characters. Nor i draw them, I just photomanipulated some pictures.
