献丑献丑！

Please do not laugh at my performance!

献丑？啊，拜托。你可以试一试嘛。

Caught dead? Ah, come on. You can have a try.

我也认为献丑才是真道理啊！

I also think show oneself up just is true truth!

先生大名，如雷灌耳，小弟献丑，真是班门弄斧了。

Your great name long since reached my ears like thunder. I am ashamed to show off my incompetence in the presence of an expert like yourself.
