When do you use the robuddys?

[ju45he]

I'll play sillycons or RD and be trying to constantly fit them in everywhere I go. I try and sell them to people for various reasons, purposes, and even let them customize the buddy a bit. Most of the time they say no though, and I'll just be setting them to heckle on everyone I dislike. Sometimes I like to make a horde and tell people to punch me for a big surprise, and they'll get gassed, tased, blinded, pied, and drugged in a second. 

I'd like to hear how YOU use them, or why you don't use them and let them collect dust.
