Tigers... pfffft.
I'll make you sick.
Borg will assimilate you.
Aliens will probe you anally.
Platypi will, jeez I dunno, lay eggs on you even though they're mammals.
The Techie will install your CPU without a heatsink and fan.
And GF, of course, will give you a nasty plague of cooties.
Humans rule, Tigers can SUCK IT!
