In Iorich when Vlad goes to his old office, hides in the corner thinking invisible thoughts, and startles Kragar so badly he almost screams.
In Issola: over the course of two chapters, Vlad manages to make Teldra and Aliera blush, embarrass Morrolan and Sethra, leave Verra speechless, and get a laugh out of both Teldra and Sethra.

In Taltos, Vlad and Morrolan are journeying to Deathsgate Falls when they encounter a band of cat-centaurs (feline lower bodies instead of equine). Vlad breaks the silence with a snarky comment. The leader of the band, Mist, jokes back. Over the following conversation, several of the cat-centaurs turn out to be as much a bunch of wiseasses as Vlad, if not more so, until they're all straining to keep from losing it laughing.
