A brown joke.

Uzer comes to Sisadmin and asks:
What is the difference between Win95 and Win98?
And he replied to him:
- In 95m of errors must be multiplied by 95, and in 98m - respectively by 98.
Uzer (dreamingly knocking his head into the ceiling):
Win 3.1 was so good, without mistakes.
and Sysadmin:
The idiot! This means that of the three users only one survived!
