WWE filed to trademark two phrases related to WrestleMania 36 back on Friday, March 20th.

"Too Big For One Night!" is a reference to WrestleMania 36 airing over two nights due to the coronavirus pandemic. April 4th and April 5th is when we'll see Mania air.  

WWE also filed to trademark "I Wasn't There" for WrestleMania 36. This is a reference to WrestleMania 36 being taped at closed-set locations with no fans due to the COVID-19 outbreak.

#WrestleMania 36 will be historic event in #WWE history, and you won't be there! Declare to the world that you did your part and stayed home with a new “I Wasn’t There” tee at #WWEShop. #Smackdownhttps://t.co/8a60F8I5zs pic.twitter.com/jTwRwGVy60
