I have heard this joke from my friend. I always wanted to write it but I was not able to find the source of the joke. This joke I have located on DavidM’s Blog on SQLTeam.
It is March 1st and the first day of DBMS school
The teacher starts off with a role call..
Teacher: SQL Server?
[Silence] Teacher: MySQL?
[Silence] Teacher: Where the hell is MySQL
[In rushes MySQL, unshaven, hair a mess] Teacher: Where have you been MySQL
“Sorry sir I thought it was February 31st”
