Take everything your senior but not executive direct reports write up at your request, make a copy of the docs, then share the copies with your executive peers as if they are your own words and ideas. When your direct reports ask for an update on the project, or want to know why no one has commented or engaged on the write-ups they created, ignore them.
Ask your direct report to do all of the prep work for a critical project that they are most qualified to run and oversee, ask them to share the pre-reads with a decision making group, invite them to the kick-off meeting, tell them five minutes before the meeting starts not to say a word during the meeting, or else.
Show up 20 minutes late to a 30 minute meeting, then spend the next 20 minute talking at the group, allow for no interruptions, keep everyone over time.
