The most amusing animal is...

We'll call this guy Doug.

The platypus of course. Not only is the word itself fun to say, these little guys are so weird looking one can't help but laugh. It's as though they were created from the spare parts bin.

To reinforce the fact that I'm a total nerd, one thing that I enjoy about the platypus is the fact that the word ends in an "s" which allows me to bastardize its plural form as "platypi," which I find equally as humorous as the animal itself. What are some other words that end in "s" and sound funnier when pluralized with an "i" at the end? Thoughts?
