Get wet
Prepare for the complexities of "Hot Tub Time Machine 2," opening in theaters this weekend, by boning up on Albert Einstein theories — or simply rewatch 2010's "Hot Tube Time Machine" with John Cusack and Rob Corddry. 6:45 p.m. Friday, Comedy Central
False alarm
"Undercover Boss" comes to Minnesota as Todd Pedersen, the founder of Vivint, a residential security company, visits a St. Paul monitoring center in disguise. Watch to see if the stress of taking calls makes his fake hair fall out. 7 p.m. Friday, WCCO, Ch. 4
Motown ministers
Say a prayer for "Preachers of Detroit," a new docu-series about seven world-renowned ministers trying to keep the faith alive in a struggling city. Pastor Don William Shelby Jr. is not the same person as the WCCO ex-anchor — although our beloved broadcaster does believe he can walk on water. 7 p.m. Friday, Oxygen
The big show
Expect Neil Patrick Harris to open "The 87th Annual Academy Awards" (6 p.m., red carpet; 7:30 p.m. main show Sunday, KSTP, Ch. 5) with a big musical number — and for "Boyhood" to score well. The most intriguing battle: Michael Keaton vs. Eddie Redmayne. And don't forget to check out "Jimmy Kimmel Live!: After the Oscars" (approximately 11:05 p.m. KSTP, Ch. 5), which always has a few star-studded surprises.
