Well, you know the drill - puns are my vice. It was a wrench but I managed to avoid calling anyone a tool. (It's probably at this point someone hits me over the head with a crowbar in order to get me to shut up...)
Eh, when you get into the nuts and bolts of puns, hammering in the point too hard makes people clamp on to the outrageousness of your word play and complain more than a bit on how you didn't scale it back. If it really starts to grind someone's nerves, then you start getting called "caulk" or "square," and then it's really just out of hand. I mean, I guess by then you know when the jig is up, but it's best not to let it get to awl that.
I think that's an acceptable amount of puns, but if you tell me it isn't, I'll most certainly call you a plier or a hack (saw). Grommet.
