Anything and everything with gags in it
That's never really an issue, I don't think. If it is then it's probably just time to buy new socks/panties/whatever else.

oh my god yes
People ask me, "Hey, don't you have a gag about your ex-wife?"
And I say to them, "Only when I want five minutes of quiet!"
Just this one
I have no idea what that is, so probably not
