First some vaguely sensible sites:
The
Crossword Tools anagram creator. For example, Edinburgh comes out
as "Ugh! Inbred." You can only find one at a time without
paying to join, but they are usually very funny.
Or how about a game of Hangman
if you like spelling games? Sometimes US spellings unfortunately...
Or if you fancy yourself as a trivia quiz expert, you
could try these Triviaplaza
quizzes on subjects like pop, films, geography etc.. If, on the other
hand, you want to play against other competitors, why not try Action
Quiz? Don't worry, you can make up a screen name!
Or play
Mahjonng online - just select the doubles to remove free tiles until
you are stuck or they are all removed?
Or...
The internet is also full of funny, pointless things
to do, so here are just some of them if you are really
bored:
Upload a photo of yourself to the Devolve
Me website and see what you might have looked like as an early human!
Pop
virtual bubblewrap - pointless, but very soothing!
Turn
a web page or web site into dialects e.g. Cockney, Swedish Chef
or Jive - for example try doing it with this page! You can also write
your own text to be dialectised.
Shoot
at coloured balloons...
Play
Yeti Sports Olympics online...
If that's not silly enough for you, why
not learn Klingon? Mind you, that might just be useful if you go
to a Star Trek Convention...
nuqneH!
