all trips are "funny".Especially shroom trips.SOmetimes they are scary,but for the most part everthing to me just seems so stupid.Everything is all over-exaggerated and out of proportion.Sometimes i like going out into public(if im in control of myself) and just laughing at people.......Little kids,old people,dumb people,drunk people.
but to answer your ? i can think of 3 funny times,althought there were countless ones

1.being arrested with 3 of my friends on dxm at one of the great lakes<---dxm

2.seeing my friend nodded out on my toilet with the lights off<-----shrooms

3.almost rear ending a cop on a country road going up a hill,because he was driving so slow.Okay,we didnt quite almost rear end him,but we were all on acid and had acid on us,and the cops car was right there man!!you know!!luckily he was in front of us.But he drove so slow,we didnt know what to do.We were all facin and jjust like "do we pass him,cuz hes going so slow,or just stay behind him and wait till the end of the road".Needless to say,we did the smart thing and stayed behind that fuckin piggy.And at the end of the road we turned the opposite way......home free to the boonies!!!
