Note Before: lots of pix
edit: lots of people are thinking that this is an exploit to destroy a mount, this is not and please read my 2nd post for a clearer explaination
edit again: making a fraps for those people who don't seem to understand
I was messing around with my Grand Ice Mammoth which can carry 2 people around with you.
The greatest thing about this mount is that you can take any amount of fall damage and live (just like the chopper/traveller's mammoth) but here we go.
If you know the exit in the dalaran Sewers, this is where the fun begins.
1. Get someone on your mount
2. Go to the Dalaran Sewers Exit
3. run off and jump
4. Land on the platform below
5. When you land, if you land close enough the mobs will proxy aggro and do a knockback which will knock people to their death below.

Yes, ejecting people would have the same result, but it's not as creative or funny.
