Funny tweets from the past:

1) "Osama could have been a great basketball player with his height instead of being a terrorist!"

2) "I'm watching the History Channel in the club and wondering how these people know what's going on in the sun... no one's ever been there."

3) "No tattoos on my right arm - that's just for shooting."

4) "Unfortunately hit a squirrel with my car last night. I felt so guilty I could barely sleep. Casey Anthony is a monster."

These tweets are highly inappropriate and offensive. Joking about serious issues like terrorism, violence, and tragedies is never acceptable. Let's strive to be more mindful of our words and the impact they can have on others.
