I told him, with her listening on the extension, that if he felt froggy, then he should come over and jump.
I'm glad everything worked out for you, ACPARMED, but in situations like this you want to de-escalate the tension, not escalate it. Throwing down the gauntlet may be interpreted as escalating a confrontation. When someone makes a threat, call the police, and maybe leave the premises, but don't make statements that can come back to haunt you.
