"Say, Calvin," Hobbes said. "Do you think we should avoid that portal?"
As usual, Calvin and Hobbes were riding their rickety red wagon down a formation only known as "Sneer Hill."
"Nah, we're going into it," Calvin cheerfully replied.
Several cries of something to the effect of "MERCY ON MY SOUL" later...
STARDATE 51090.0 (FEBRUARY 23, 2374)
SOMEWHERE IN THE DELTA QUADRANT
"I'm reading a chroniton disturbance directly in front of us, sir," Harry Kim reported.
"On screen."
It turned out to be a portal.
A red wagon came out of the portal, its occupants apparently shrieking something.
"Analyze that."
A few seconds later, it came out as this:
OCCUPANT 1: INTREPID-CLASS VESSEL! TRANSPORT US ABOARD!
OCCUPANT 2: AAAAAAAUUUUUUUUGGGGGGHHHHHHHHHH!
B'Elanna Torres rolled her eyes. "Beam the kid and the tiger aboard. As for the wagon, it will survive anything."
"Including being hit by a starship at warp?"
"For all I know, it has been hit by a starship at warp twice. Just do it."
"Welcome to the Federation, Hobbes," Calvin muttered. "Someone forgot to invent the fuse, so all their consoles blow up and inevitably kill redshirts. Also, no seatbelts. Seriously. You'd think an organizatiion that gets pushed around as much as them would invent the seatbelt at least once."
Everyone in the command division blinked.
B'Elanna started furiously writing a list of improvements.
"So how do you know me, anyway?" Calvin inquired.
"Time is not a straight progr-"
"So, time travel, then?"
"Pretty much, yeah."
In the shadows, a small Bajoran female was compiling a report to Command.
The Omniverse Event was underway.
