Some teams feel the need for a signal to indicate the end of a standup. Perhaps this is most suitable for a team comprised of recent agile adoptees.
For the more cynical of us, the “On Belay? / Belay On” question & response makes for a thought-provoking metaphor. It might be even an appropriate metaphor if every team-member has your back, but it might wear thin if there’s an undercurrent of mistrust.
In the post All For One, One For All - Signal the End of Your Stand-ups, agile coach Ken Clyne urges us to have a clear sign that standup is over. I'm torn about Ken's suggestion. I agree it is sometimes helpful to have a signal for the end of standup.

Perhaps Markus sensed we were a joyfully cynical lot that could only abide a minimalist's touch.
My caveat is to be careful of gratuitous ceremony. I think Markus had it right.
I caution against the potential for rah-rah cheesiness in your standup. It's probably yet another flaw that has hindered my professional advancement, but I cringe at the first sniff of scripted ceremony.
