Funniest/Weirdest examples of Relationship Voice Actors

As the title says. You know, when you see some show and you recognise the voice actors of two related characters who also voiced other two related characters in other shows? That's it.

Since I'm Italian, all of these examples are from Italian dubs:

• Hitomi and Sayaka are Diamond Tiara and Silver Spoon
• Rainbow Dash and Gilda are Dexter and Mandark
• The Ninth and Tenth Doctors are Ultra Magnus and Rodimus Prime
• Fionna and Prince Gumball are Charmcaster and Clancy

Or Manga & Anime.
