Also, I should probably comment, I don't really know all that much about Indo-European languages, so much as Uralic/Finno-Ugrian languages. Even then, I'm pretty much Hooked on 'Finnics' (lulz, couldn't resist).

Finnic first person pronouns look like: minä/mä, mie, ma, mun, mon

Finnic second person pronouns: sinä/sä, šie, sa, don, ton

Also, some cursory googling lead me to: http://www.google.com/search?hl=en&q=indo-uralic&btnG=Search

Hmmmm...

Dan: Finnish is Finno-Ugric, just like Hungarian; Northern Sámi, Estonian, Karelian. They're not on this tree since they are not Indo-European, although theories point to Proto-Finno-Ugric as being closely related to Proto-Indo-European. I've heard evidence cited being along the lines of 1st and 2nd person pronouns being similar, as well as verb suffixes involving those:

English: I, me, my; I am. You, your (thou). You are/Thou art.
Finnish: minä, minun; Minä olen. sinä, sinun; sinä olet.

Most of Indo-European languages show some sort of nasal consonant as 1st person, and some sort of 'dental'/alveolarish consonant for 2nd person, so we have those in the above example, as well as these other 1st person pronouns:

1st Person

French: je, me
Spanish: yo, mi
German: ich, meine (sp?)
Russian: ja, menja (excuse the transliteration)
Swedish: jag, mig/min/mitt

2nd Person:

French: tu
Spanish: tu
German: du
Russian: ty
Swedish: du

Mysterious, right? Anyway, there's probably more evidence for such a relation, but I'm not going to try to list it exhaustively. Basic point: Finnish and Hungarian are not I.E. languages. :)
