Get the The Bull mug.
Chicago basketball team that used to dominate but now is on life support. THE sports team of the 1990's, led by Michael Jordan, arguably the greatest basketball player of all time. Set the record for most wins in an NBA season at 72.

Now the team rests its hopes on Eddy Curry and Tyson Chandler, two highschool-to the pros centers. One (Curry) is seemingly too fat while the other (Chandler) is too weak and thin. Both have to use google search engine to find the basket or their defensive game.
