What's the worst excuse someone's ever given you?

Someone just told me they couldn't call me on their 30-minute drive home from work because their toilets at home stopped flushing amd they were stressed out about the cost of getting them repaired. After I didn't reply, he added that he also had hemorrhoids that made it painful to use the bathroom but he was embarrassed to tell me that that was the other reason he couldn't call me.
