Missing Sub in #1098 (2012.03.25) Tanaka's Breakdown

Hi everyone
I am a gaki fan from China, recently I watched ep #1098 (2012.03.25) — Tanaka’s Breakdown with English sub, but at the end, there are two lines without subs,
the missing lines are:"張りがないもん"and“感情が,無理してるから,張りがないもん", I’ve tried Google translate, but doesn’t seems right, can someone tell me what are those lines mean.

Thank you very much
