The only changes that can be seen are that Idiotest reruns replace It Takes a Church starting Thursday, May 21st at 8pm and 11pm ET. The last new episode of It Takes a Church this season will air May 14th at 8pm. The Newlywed Game replaces It Takes a Church Saturdays at 1pm.
Lie Detectors remains new Wednesdays at 9pm, 9:30pm and Saturdays 11pm and 11:30pm ET through the week of May 18-24.
Additionally, rumor has it new runs of The Chase and Chain Reaction may be paired back to back on Thursday nights this summer. I have no further information on why Thursday night or starting when; just heard the rumor. Stay tuned.
