Those jokes were submitted by @Gundog. To see this for yourself, r-click a blank area of the page and select "Page Source", or whatever is appropriate for your browser. You will then see the desired text encapsulated within HTML cr@p. I used the Find and Replace feature in Notepad to remove the HTML formatting.
To avoid this problem in future, r-click the composition window and select "Paste as plain text" (or Ctrl-Shift-V), or whatever is appropriate for your browser. This will ensure that any formatting is discarded (eg HTML, fonts, bold type, italics, etc).
To be fair to @Gundog, this forum's software is plagued with problems. In fact I've given up trying to use the quoting feature. I'm also tired of having to correct certain characters, eg tildes, quotation marks, em dash (long hyphen), etc.
