[[Alliteration Time travel's tricky;
Try to talk tenses, then trip.
Today? Tomorrow?]]
[[Self-Demonstrating Article You think you were first
But I will be before you
In half an hour.]]

Past, future and present tense
This does not suffice.
When Unstuck in Time
One must sort out in advance
What tenses to use.
[[Overly Long Gag We haven't yet been
Entering from tomorrow
But we soon]] yethave.
