I have never seen an actual platypus.
@Talyaa Are we sure they actually exist? Early British naturalists were sceptical of the veracity of the first preserved specimens they received, and every fresh fact I learn of platypuses makes me wonder if someone isn't having me on. Electrolocation, you say? Ok...and they have venomous spurs too? Hmm.
HOW MANY PENISES???
@Talyaa it's a divisive issue.
(I rejected more offensive goofs, mainly puns, partly on the basis of decency but mainly because I'm never really sure how to pronounce "cloaca")
