I love dogs…but ten is kind of getting on in years, so I’ll play it safe. Six.
Next: Snotty college aged aspiring writers
Oh god. Don’t tell me I killed it. Er…bump?
Show me the room… 
Snotty college aged aspiring writers…
two would be funny because they would piss each other off. Three, two would gang up on the other and devour him/her.
Four…
eek that’s scary already.
Roadwalker seems not to have left a new lifeform for us to fear, so I’ll contribute one here:
Cassowaries
I don’t trust birds that can’t fly–it’s like people who ride busses–what’s wrong with you that you couldn’t get a drivers’ licence ;)?
1 is interesting but 2…I’d wonder what they’re cooking up in their bony head gear.
Next: Drunken dickheads, who gave everyone a hard time in three different bars, two of which they were 86’ed from, all night long, then you find one of them in the shitter of the last bar you go to lying in a fetid puddle of piss and whatall with his arms wrapped around the toilet and face in the bowl and when you walk in he looks up at you with a sneer on his vomit-soaked face.
Drunks:
Normal drunks - 9
Canadian drunks - 5
Welsh drunks - 4
Welsh drunk with a Womble fixation - 3
Ok… how about Owls
I like owls. Owls are wise. It was an owl that finally answered the age-old question of “How many licks does it take to get to the Tootsie Roll center of a Tootsie Pop?” For that reason I’d take, ummmmm, 50 owls. Any more and I’d feel like I was at a Who concert.
crickets chirp, leaves rustle
Ahem, yes, well I suppose it’s up to me to provide the next fauna.
Um, I’ll take camels for $500 Alex.
One camel would be fine I think (The animal not the cigar right?)
Two would be interesting. and finally three would be scary 
Next up Siamese Cats
- I love animals, but all of them rubbing themselves on my legs and covering me in cat fur would get just a little annoying.
Next: PE teachers
Ugh. That is one creature I can get enough of.
I’ll say two because I think one would be on me to score a goal or do a few more push ups. Two, hopefully of different genders, just might start to argue, and then maybe breed (a la “Love Story”) if I’m lucky.
Next: Poisonous Tree Frogs (We haven’t done frogs yet, at least not the tree frog variety…)

three, more than two and you would run out of gloved hands to hold them.
(I’m still scarred of the college are writers)
next up…
(I thought who concert was funny)
okay next up:
those little bugs that bang into your ceiling at night when you’re trying to sleep.
I have no experience with bumping bugs so I’ll say 100 as long as I get to bring 25 spiders (Could get kinda scary once the spiders run out of food though…)
Next: Doobie Brothers (with instruments)
Um…well, it’s a small room, so I’ll go with ten. Any more and it might start to get loud.
Oh and I hate those bugs.
Next…Little ankle biting Yorkie terriers
One’d be enough for me, what with the ankle-biting and all.
Lessee…pompous middle-aged wizards?
Hmmmm…might be able to convince them to do my will…use enough flattery and you can get practically anyone to do practically anything. I’ll take at least 100, to help me take over the world.
And the next one is: giant man-eating venus fly traps
Two Venus Flytraps. If there was only one I could just keep tossing it ground beef contaminated with E Coli.
Next: Xtian fundamentalists.
Well my b/f’s family are Pentecostals… so I think I could handle eight or ten as long as they didn’t start proselytizing.
Cats in heat.
I could only handle one fundie, they scare me on street corners enough that I’ll cross the street.
Next, the people the fundies vote into congress
