That's ironic. An Asian making Asian jokes.
Unless of course it's meant to be self-deprecating?
Although, there is one point of contention I have, though... I think that the Asian accent usually only leads to mispronouncing L's as R's, but it doesn't work the other way around. The problem is that they hear them as the same sound, so they make "R" consistently, whether an R or L is being voiced. It wouldn't make sense for them to just be reversed. I've only ever heard Asians mispronounce L as R, and not vice-versa.
I've noticed that a lot of people seem to think that Asians always get Ls and Rs confused, and make Engrish jokes that don't really make sense as a result.
