I've noticed a lot of discussion recently concerning the fate of Spike 
and Buster's dad, Irving 'Sparkplug' Witwicky, or more specifically, his
absence after the Movie. Well, what else could I come up with, but...

THE TOP TEN REASONS WE NEVER SAW SPARKPLUG 
AFTER THE MOVIE

10. He fell asleep in Ultra Magnus' chair one day, and Ultra doesn't
always look where he sits...

9.  He stood right in front of Twin Twist's blaster and said, 'Bet you
WON'T!!'

8.  Worked out where the real money was and switched sides.

7.  On the 'occupation' part of his tax return, he wrote, 'I live in a
volcano and fix giant robots from outer space who turn into cars,' 
and has been receiving treatment ever since.

6.  He eloped with Chip.

5.  He eloped with Shockwave.

4.  He sold his story to the tabloids, and can now be found in the 
South of France.

3.  He got drunk and tried to chat up Nightracer.

2.  Showed up Wheeljack *once* too often...

AND THE NUMBER ONE REASON WE NEVER SAW 
SPARKPLUG AFTER THE MOVIE...

1.  He talked about the 'alien robots' near a middle-aged guy who smoked
a lot of cigarettes, and he hasn't been seen since!
