Bob's Your Uncle?

I don't know if it's a commonly used phrase, but WTF? Bob is SO not my uncle. Let's translate it, just because I have nothing better to do:

Pirate Speak: Yarrgh matey, Bob be yer uncle!
Dutch: Gast, je oom heet Bob!
Tub says: TUB!
German: Dein Onkel ist ja Bob, Jawohl! [Insert racist nazi joke here]
Ninja Language:
Harry Potter: Bobbius Avunculus!
Super Upperclass Dandy British: Bob. Rah!
Gnarly Australian/Hawaiian Surf Dude: Duuude! Bob's a sweeeeet name...
Grandpa Speak: I knew a man named Bob once. Nice guy... But he died.
Zombie: HARHOJEBYHRMGWS! bob
Nickelodeon: SpongeBob's your uncle!
Joseph DuCreux: Robert is your paternal or maternal male sibling!


LAAAAME!
