Good evening(in fact, it's morning in chinese time). yeah, i took this sentence out of a conversation. more about this coversation: ==================================== Chandler: Bad news. I watched the tape and passed it along to my bosses and they weren't interested. Joey: (sounds disappointed) Oh. Chandler: (Hands the tape back to him) I'm sorry man. Joey: (looks at him suspiciously) But, ehm... you watched the tape? Chandler: (sounds nervous) Yeah! I... I... I liked it! (Joey continues to look at him suspiciously) But, ehm... my bosses didn't go for it. Stupid sons of bitches! Joey: (sounds confident) You didn't watch the tape. Chandler: (looks surprised) What!? Of course I did! Joey: Look, it's one thing not to cast me, but to lie to me? Chandler: I'm not lying to you, I watched it! =========================================== but just don't know what the word "cast" mean. yeah, that's a play my friends recommend to me to leanr English. Good luck on your learning adventure! Thanks

Good evening, It appears that you may have taken this sentence out of a conversation that gave it more meaning. You should look at the entire conversation and then draw your conclusions from that/ Knowing what I know about "Friends" it was most likely meant to be funny or humorous. Good luck on your learning adventure!
