humorically challenged

i think i am losing my sense of humour.
from tasteful jokes to....stupid...lame...words.
an example:

chung: yo my school (u of ottawa) has the best programme of crim and law in the country
grace and tim: suuureee says WHO?
me: says ANDY CHUNG?!
tim: yeah says ANDY CHUNG?! HAHA ha ha
grace, tim, gendi: Hhahahahhahahaha
gendi: (in an attempt to "expand" the "joke") ha ha..says..donald TRUMP! (because it's suppose rhyme with andy chung)
all: .............
me: ...............
...................................
.................................................................................................................

I mean...before when i use to tell my witticisms, people would laugh..or at least..find it a bit funny..
but now...i say a joke. and people just roll their eyes and cringe at the cheap quality of it. like..it's just not funny. it's lame.
oh poor me. oh humour where art thou?

it must be that people are just not on par with my level of joking. tsk tsk.
i must be in denial..or other people are, they're just jealous of my chiu kup humour.

are there words that sometimes make you smirk a little? There are some words that makes me laugh when i think about it...
like...the word "globular" (g-l-o-b-u-l-a-r)
say it many times, globularglobularglobularglobularglobbobgoolernoelrboerinfaeirjael;rjasr....BLOG-->! HAHA! (see, not funny)
it's just such a weird word...it reminds me of..goo, like flubber. or...golf balls
