The seven potters scene

The more powerful wizards were the protectors. Moody doing magic as Harry would been obvious that it wasnt Harry

I wonder why they didn't just all disguise as someone OTHER than Harry. They could all be disguised as Arthur Weasley, for example.

Curious how the voice doesn't change, when every other physical aspect (like Harry's poor eye sight) is imitated.

On that note, now the girls know what Harry's peepee looks like.
