Imogen says: It takes a greater proportion of time and effort to type, but I'll take it!
Fred says: Yes, iguana is easy
Fred says: Frog is tough
Imogen says: Well I suppose I must be thankful that there is no such animal as a Ficklelinkidinkidunk.

Imogen says: SHIT
Imogen says: Something must be done!
Imogen says: *fetches gun and hunting hat*
