While the Queen was away in Scotland last month, one creative Grenadier Guardsman took the opportunity to add an unusual twist to his usual sentry duty.
He also pauses to give the sentry box a quick wipe.
At several points he freezes and shows a remarkable sense of balance.
Watch the whole thing here!
Reaction beneath the video was split.
Others were more sympathetic to the Guardsman.
Not everyone is as amused by his antics though, and the Ministry of Defence has confirmed it is investigating the stunt.
