I guess they could be shaped like thought clouds too and have 3 small spherical bubbles below them.
A lot has been written about speech balloons here. But i couldn't find any mention of regular helium balloons with pointy horns coming off the bottom.
The balloons could say, "I'm happy" and then you could go around being happy all the time to avoid the irony and embarrassment of being sad and having an "I'm happy" balloon.
In the linked idea [AfroAssault] complains of "using cardboard" (to write a thought balloon), "it takes really long to have to write down all the words, and then you can't reuse it. "
If you had an "I'm happy" balloon and you just stayed happy all the time, you wouldn't want to say anything except, "I'm happy", and it would always be true, and you wouldn't have to write anything new or change it ever. You could just tie the I'm happy speech balloon to an ear so that it floated above your head and you could walk around smiling and being right and not even actually moving your vocal chords but still communicating in real time with everybody.-- JesusHChrist, Jan 07 2006 Talking balloons Real_20Talking_20Balloons [JesusHChrist, Jan 07 2006] No speech bubbles but thought bubbles.
