When Lucy and Ricky teamed up?(Lucille Ball and Desi Arnaz made quite a comedy team in these episodes)Usually it was Lucy/Ethel ,but on several occasions it was Lucy/Ricky.Like in the one where they became ,in Ricky's own words"We are going to become the two most obnoxious tenants ever!"And of course,the hysterically funny "The Young Fans",where they made themselves up to be REALLY OLD,in order to scare off their young fans,Arthur(the late Richard Crenna)and Peggy(Janet Waldo).And when they teamed up when Little Ricky's drumming drove Fred and Ethel crazy (Lucy:"Go ahead and play,son!").Remember these?

I remember them they were good especially the one where Lucy and Ricky team up to try and break their lease on the apartment.

I like the one where Lucy and Ricky get handcuffed together.
