lazy scientist and deleting one word after another in a sentence can lead to a nice story - two jokes

Ever noticed how deleting one word after another in a
sentence can lead to a nice story?
Here's an example:
...
"Oh jack plz dont touch me at all.. !"
"Oh Jack plz dont touch me at..!"
"Oh Jack plz dont touch..!"
"Oh Jack plz dont..!"
"Oh Jack plz...!"
"oh Jack..!"
"Ohh... .!
;)
