Tubes take you to a new level of strangeness!
On youtube many strange and sometimes wonderful things can be found. However in this case we have role reversal, almost perfect lipsync on two videos.
For example mashups, this is an execellent example of this kind of thing.
Silly stuff:
Rammstein … playing …
Bayern des samma mia
Then the revenge:
Haindling … playing …
Du Hast
Like that was ever going to happen in either case. 
If you are using a free software distribution, don’t install “Flash” use “gnash” or “clive” to access youtube!
