Random AIM exchange. My buddy was sending me macintosh characters over AIM to see which ones would break and not show up on my AIM client, and the following occurred:

Tobin00: because the fourth character you typed showed as an 8 on my side
Tobin00: but i got no warning
freston0: Aha! It's this one: 8
Tobin00: yes, that is an 8 :-)
freston0: No, it's an infinity symbol.
Tobin00: awww
Tobin00: that sucks that i can't see infinity
Tobin00: i should meditate more
freston0: hahahahaha
freston0: Asshole.
