NUMBER PUZZLE

I sent out a puzzle to my colleagues recently. And honestly, I thought the answer would be completely obvious after some thought.
It turns out I may have been mistaken. To a Dutchman it could be obvious – we’re notorious number fiends - but my colleagues are NOT Dutch.
Not even close – the Chinese / German / Indian / Jewish / Hungarian / Scottish / Swiss quotient here is rather on the short side.

[Note: There are no Vulcans or Ferengi on staff that I know of. But they may be in drag.]

Yes, one Indian was on the receiving end, but as she strenuously avoids all things Gujerati, including even their repulsive thought processes, she too was baffled.

[She isn’t Punjabi or Bonglowalli either.]

What do these numbers represent?
Or, what is it that makes them a logical series?

1, 3, 4, 5, 7, 8, 9, 12, 13, 16, 17, 21, 25.


Surely you can see it?

No?

Here's a MAJOR clue - the second series. Same process as the first.

1, 2, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 28, 29, 30, 32, 33, 34, 37, 38, 41, 42, 46, 50.

Please think about this. If absolutely necessary, I will post a THIRD series of numbers in a few days, which should make it glaringly, blatantly, over-the-top easy to figure out.
You will slap you're face and go 'tisssch!'


So far, the responses have been educational.

Person A.: "I'm not that smart."
Person C.: "These are the numbers of your favorite hockey players."
Person D.: "You don't know how to count, and have trouble getting all the numbers even!"
Person E.: "The fingers you hold up when ordering dimsum."
Person G.: "Lyrics to a song by ‘They Might Be Giants’. "
Person H.: "How many zookeepers it takes to hold up the python."
Person J.: "Total and complete paranoia! You need help!"

[I haven't paid attention to hockey since high school. Imagine, please, the sheer insanity of giving thirty hormonally overloaded aggressive teenagers a curved piece of wood and a hard ball, and telling them to spend the next two hours running around a muddy field with NO supervision. I'm surprised not more of us ended up crippled for life. So no, there is no hockey connection.]


If you, dear reader, have the answer, please post it to my LETTER BOX.
What you write will not be shown, so as not to spoil it for anybody else.
Everybody who thinks they got it will be acknowledged when I give the solution.
At which point, I expect that there will be howls.
