Per Brian:
This might be a good idea for a new word game. Add, drop or change a single letter from the previous word and make a new word. This game might actually have a winner which would be when we have totally stumped the chump and nobody can think of a new word.
I’ll start:
CHUMP
(Remember, you can only add, drop, or change a single letter.)
Looks like I have to put it in a sentence for it to stick…the word alone won’t post.
HUMP
HEMP (min length posting)
Temp–
No abbreviations allowed, you chump!
Ok then.
HEMS
That’s more like it, Sam! 
GEMS
Gums
sums
bums
Mind out of the gutter
Who, me?!?!? 
burs
burst
wurst – Yummy, missing Germany now. 
Oh come on we gotta have some rules here. Words can be in any language? How about sub Saharan tribal dialects? how about industry specific acronyms?
Wurst is an Ameican word, too. 
worst
worse
worsen
